Grinding out 50 NPC wins without eating a single loss sounds like a tall order, but it really comes down to picking the right shell and knowing exactly what you’re doing with it. I’ve run this list enough to know it works — the plan is fast, the damage snowballs, and the recycle engine keeps you swinging every single turn. If you’re tired of coin-flip duels and just want the win counter to tick up cleanly, this is the deck I keep coming back to.
The Decklist
Here’s the exact 50-card recipe. Every card sits at four copies except Fistronk, which only needs two — so 12 distinct creatures make up the list. Build this in the Workbench and you’re ready to go.

| Card No. | Name | Copies |
|---|---|---|
| No. 241 | Shero | 4 |
| No. 253 | Kuramigo | 4 |
| No. 265 | Aquariff | 4 |
| No. 277 | Fistronk | 2 |
| No. 421 | Jellyclean | 4 |
| No. 541 | Mosquit | 4 |
| No. 757 | Batran | 4 |
| No. 769 | Dasko | 4 |
| No. 1105 | Ghost Lantern | 4 |
| No. 1201 | Swooping Blade Crow | 4 |
| No. 1225 | Dense Flower Fairy | 4 |
| No. 1333 | Little Flame Chick | 4 |
| No. 1345 | Flamepeck Chick | 4 |
How the Damage Engine Actually Works
Your win condition is two cards: Little Flame Chick and Flamepeck Chick. You run eight of them total — four of each — and everything else in the list exists to feed them.
Both of these creatures gain attack power on the turn they hit the field, scaling with the number of their own kind sitting in the graveyard and on the board. That’s the whole trick: the more of them you’ve dumped into the graveyard, the harder they punch. Get all eight into the graveyard and each one you revive comes out swinging with serious firepower. That’s why the deck runs so many ways to churn through its own library.
The Opening Turns
Setup starts with Dasko. Use Dense Flower Fairy to search and Jellyclean to draw, digging through your deck and setting up your graveyard in the process.
Your target is to fire Dasko a combined total of two times across turns one and two. That’s enough to move all eight Little Flame Chick and Flamepeck Chick cards from your library into the graveyard — exactly where you want them.
One caveat I learned the hard way: any of those eight that happen to be caught inside your Guardian’s four cards can’t be used until your own life total drops. So keep an eye on how the library shakes out — the engine stalls a little if too many of your key pieces are locked behind Guardian slots.
Reviving and Swinging Every Turn
Once the graveyard is stocked, it’s a loop. Lean on the reanimate abilities of Mosquit, Batran, Shero, and their evolved forms to pull Little Flame Chick and Flamepeck Chick back from the graveyard each turn and attack with them. You keep bringing bodies back and keep dealing damage.
Don’t get sentimental about the board. A Flamepeck Chick that already attacked, or a fully evolved Shero, does hit a little harder than the rest — but it isn’t worth protecting. Overwriting and discarding them without hesitation keeps your deck cycling at full speed, and a fast-cycling deck is far more dangerous than a tidy board.
Battle and Tournament Notes
While a tournament is running, you can’t start a normal battle — worth knowing before you go looking for a duel and wonder why nothing triggers.

As far as I can tell, wins you earn while participating in a tournament also count toward your total, so those matches aren’t wasted progress.
To start a regular duel, sit down at a chair occupied by a single person and select that person’s individual desk. That’s all it takes to get a match going.
One annoyance: your opponent hands you a pack as a gift after every match, and it gets in the way. Set up a dedicated pack-facing machine for this — and here’s the subtle part: don’t start the duel while the machine is running. Once the match ends you’re forced to hold the pack, which means you can’t interact with the machine anymore. Better to have it parked and ready than mid-run.
Building the Deck
All of this comes together at the Workbench, where you assemble the deck itself. Get the 50 cards sleeved up and the rest is repetition — mulligan for your setup cards, dump the chicks, and let the graveyard do the heavy lifting.
Conclusion
It isn’t a complicated list once it clicks — search, mill, revive, repeat. The 50-win run is really just a matter of letting the engine do its job match after match, and you should be cashing in that undefeated run before you know it.
