Random idea for the Koa'Ki Meiru deck that will appear in the Recon Universe. If I make any other Koa'ki Meiru cards, I'll probably post them here.
MAP-Core Expander
Continuous Trap Card
After activation, equip to a face-up "Koa'ki Meiru" monster. Once per turn, by revealing an "Iron Core of Koa'Ki Meiru" from your hand, you can remove from play 1 "Koa'Ki Meiru" monster in your Graveyard. The equipped monster gains the effect of the removed monster. Destroy this card if you control a monster(s) other than the equipped monster. When this card is removed from the field, destroy the equipped monster.
