Wuthering Waves 2.4 Echo Card Duel: Fousy “No Return” Deck Explained ~ HaploGamingChef

Intro to the Prestige Echo Card Event

The Peaks of Prestige event in Wuthering Waves 2.4 introduces a fresh twist to gameplay with an Echo dueling mini-game. It’s more than just collecting strong characters—it’s about building an efficient Echo card deck that can carry you through progressively harder matches. After testing multiple setups, there's one standout strategy worth sharing.

How the Fousy “No Return” Strategy Works

This guide focuses on a powerful combo: the Fousy “No Return” deck, emphasizing Spectro and Havoc cards. The idea is simple: reach five transform activations quickly to summon Fousy. When done correctly, you can bring Fousy out as early as round one, which massively boosts your power and control.

Unlocking the Deck: When to Use This Build

You won’t get access to this exact setup early on. This deck is only viable once you’re close to the end of the main event story. It’s built around rare cards and precise combos, so don’t worry if you can’t use it right away. Focus on unlocking and identifying the needed Echoes first.

Why Fousy is So Powerful

The power of Fousy No Return lies in how quickly it can be summoned. Transforming five Echoes is the requirement, and that’s easier than it sounds once your deck is fine-tuned. Doing it in round one is rare, but hitting it by round two is very achievable with the right setup.

The Three Core Cards That Make It Work

To make this deck function, three cards are essential:

Diggy Duggee: On transform, lets you draw three cards. Having this early is key for digging through your deck fast.
Havoc Warrior: When modulated, this Echo can stack an unlimited number of one-cost cards. That stacking ability is critical to fast transformations.
Nimbus Wraith: When you use transform after modulating this Echo, it recharges your energy by one per transform. Since transforming is central to this strategy, you get tons of energy back quickly.

Important One-Cost Echoes to Include

You’ll want to stack your deck with efficient one-cost Echoes that support early transformation plays:

Fission June Rock: Transforms into a choice of three one-cost Echoes from your deck, giving you options right when you need them.
Saber Bore: Transforms into three energy points. Great when paired with Nimbus Wraith to supercharge your round.
Diamond Claw: Draws two cards when modulated. Also has a helpful perk for energy generation.
Dwarf Casawary: Gives your Echoes +1 strength for the next round when transformed.

Your One-Cost Flex Picks

You’ll only want to include one or two of these support Echoes depending on your preference:

Hocus Pocus: When modulated last, gives +2 strength and +1 CON.
Chop Chop Leftlist: Reduces opponent Echo strength by two on transform.
Vanguard Dunrock: Similar to Diamond Claw, but comes with a different perk.

Your Key Three-Cost Echoes

Here are your heavy hitters, chosen to synergize with the main build:

Dionist Knight: Transforming boosts all Echoes' strength by +2 for a round. It shuffles back into the deck rather than getting consumed.
Lightcrusher: Gives you a Dionist Knight and one energy on modulation. Keeps the buff cycle going longer.

Character Pick: Why Jang Leao Works Best

For your character, use Jang Leao. His passive draws an extra card at the beginning of the first three rounds. That gives you a better chance to get Diggy Duggee or Havoc Warrior early. His active is also strong: it lets you choose one card to save for the next round, which is great for planning your plays.

What a Strong Round 1 Looks Like

In a good opening round, aim to get Diggy Duggee and at least one Havoc Warrior or Nimbus Wraith. Use energy gains from Saber Bore and transforms to cycle your deck and draw more. If the stars align, Fousy hits the field in round one. Even if not, you’re still on track for a round-two summon.

Combo Play Breakdown

Here’s how a typical turn unfolds:

Start by transforming Diggy Duggee for a draw-3.
Use Fission June Rock to choose a one-cost Echo from your deck.
Modulate Havoc Warrior, then stack other one-cost Echoes like Nimbus Wraith or Diamond Claw.
Get recharge going so you can keep transforming without running out of energy.

The more Echoes you transform, the faster you get Fousy—and the stronger your team becomes.

Adapting the Deck for Difficult Mode

Difficult mode in Peaks of Prestige adds complications: opponents get stronger Echoes and bonus stats. While the core deck stays the same, you need to:

Play more cautiously in the first round.
Prioritize strength-reducing Echoes like Chop Chop Leftlist.
Use your character skill to hold strong cards for round two.

When You Miss Key Echoes: Making Backup Plays

Sometimes you won’t pull Havoc Warrior or Diggy Duggee early—and that’s fine. Use these backup tactics:

Rely on Saber Bore or Fission June Rock to ramp energy and filter your deck.
Use Lightcrusher to access Dionist Knight quickly.
Set up with Nimbus Wraith for guaranteed energy refunds during transformations.

Even without a perfect hand, reaching five transforms by round two is still within reach.

Energy Management Tips

Energy is the key to keeping your deck active and efficient. Here's how to keep energy flowing:

Use Saber Bore and Nimbus Wraith together for explosive energy turns.
Take advantage of Recharge perks to transform and refill your energy bar.
Avoid overcommitting on early turns—save 1–2 energy to carry over and stabilize round two.

When energy management is done right, you won’t be stuck with dead cards or out-of-turn Echoes.

Echo Positioning: Maximize Board Control

Where you place Echoes matters. Proper positioning lets you trade smartly and avoid wasted turns.

Place Fousy opposite high-HP targets to maximize damage.
Keep support Echoes like Lightcrusher or Casawary in back row when possible.
Use positioning to bait enemies into overextending, then punish with strong second-row follow-ups.

These micro-decisions separate average runs from perfect clears.

Round Two Push: Securing Control

If Fousy doesn’t drop in round one, make it your priority in round two. By now, you should have:

Several transforms ready or used
Plenty of energy through Saber Bore or Recharge
Access to strength-boosting Echoes like Dionist Knight

Get Fousy on the board, boost his strength, and play aggressively to pressure your opponent.

Echo Stacking Order Matters

A frequent mistake: stacking Echoes without planning the order. Always:

Use stat-boosters last (like Dionist Knight or Dwarf Casawary).
Start stacking with Havoc Warrior first to activate the unlimited stack effect.
Layer utility Echoes (draws, energy gains) in between for max efficiency.

The right stack order ensures your most valuable buffs land after key plays—not before.

Knowing When to Sacrifice Cards

Sometimes you need to give up an Echo to draw, trigger a modulate, or clear the board. Smart sacrifices include:

Extra Lightcrushers in early rounds
Duplicate one-cost Echoes when draw isn’t needed
Cards that don't synergize with your current transform loop

Efficient sacrifices keep your tempo high while setting up future rounds.

Dealing with Strong Opponent Decks

Harder challenges in Wuthering Waves 2.4 throw high-strength Echoes at you fast. To counter:

Focus on Echoes that reduce enemy strength (e.g., Chop Chop Leftlist)
Use your energy smartly—don’t burn it all on setup if the opponent can punish you
Always have a recharge or energy Echo ready to refill mid-round

These tips let you stay ahead of power creep in difficult matches.

Why Unlimited Stack Is Game-Changing

Most Echoes limit how many one-costs can stack, but Havoc Warrior breaks this rule. That makes it the centerpiece of this deck. With unlimited stacking:

You use transform more often
Recharge perks activate more frequently
Buff cards like Dionist Knight affect a wider range of Echoes

It’s this card that allows you to summon Fousy earlier than nearly any other strategy.

The Strength Cycle: How to Snowball

Once Fousy is on the board, your job is to push that momentum. Here’s how:

Use Dwarf Casawary and Dionist Knight to snowball team strength
Stack Fousy in the back row when the opponent’s front line is weak
Trigger modulate effects to draw or recharge and set up another strength cycle next round

You’re not just winning—you’re scaling into a hard-to-counter position.

Fousy Frontline Tactics

While back row is safe, putting Fousy in front can be worthwhile. It lets you:

Directly pressure enemy three-cost Echoes
Force your opponent to commit defenses early
Make use of his already-high strength to remove key threats fast

Just be sure to protect him the following round using energy shields or replacement Echoes.

When the Deck Doesn’t Work: What to Adjust

Not every run goes according to plan. Here's how to troubleshoot:

Too slow to summon Fousy? Increase draw Echoes or keep Diggy Duggee in opening hand.
Not enough energy? Add a second Saber Bore or double up on Nimbus Wraith.
Opponent scaling too fast? Bring in Chop Chop Leftlist for control.

A few tweaks can stabilize your win rate significantly.

Why This Deck Stands Out

What makes the Fousy No Return deck unique in Wuthering Waves 2.4:

Early access to a strong summon
Synergy between draw, energy, and strength scaling
Flexibility to adapt depending on hand

It might not be “meta,” but it offers high potential, fun gameplay, and consistent results—especially in Normal and early Difficult runs.

Conclusion: A Versatile Echo Deck Worth Mastering

The Fousy No Return deck isn’t just strong—it’s satisfying to play. With smart energy management, careful Echo stacking, and consistent transform use, this build offers powerful board control from early rounds. It may not dominate every matchup in Difficult mode, but it scales quickly, adapts to most hands, and handles both Normal and Prestige tiers well.

If you're playing Wuthering Waves 2.4, this deck is definitely worth trying out—especially if you're looking for something outside of the current meta with solid performance and some creative depth. Master the rotations, adjust your support Echoes, and you’ll be dropping Fousy in record time.
