My favorite move if I'm going first : summon Urnight, reveal Iron Core in my hand to special summon Prototype from my deck, set backrow (if any), let Urnight destroy itself during the end phase, it will trigger Prototype effect to special summon Koa'ki Meiru token (1800 ATK / 1800 DEF). This way, I'll have decent "wall" on the field without wasting Iron Core or Diamond Core
Turn 2:anki + 2 mask changes = OTK
this deck is all about aggressive playstyle with few or 0 differences, it's the worst turn 1 starter but one of the best turn 2 OTK decks.
Advantages of Koa'ki:
-Very Aggressive
-Field nuke ability
Disadvantages:
-0 defense
-Bricking (better with diamond core)
-You need combos to win so average to bad hand management.
-Zero comeback potential.
-Lose to kuriboh.
It's just a weak turn 1 starter, the OTK potential in this game is insane you know + balance is good but with balance you need 1 or 2 turns to do you OTK combos.
Better defence = more bricking
