This decklist comes from Mulciber113 on Archidekt and combines elements of reanimator, self-mill, and recursion packages to form a multi-faceted deck that can tailor its gameplan to whatevers happening in the current game
I would perhaps recommend making the ATK boost last until the End Phase, or making the ATK boost permanent, but only equal to the ATK of the banished Space Mermaid (or perhaps half of it, because even then, a Level 2 able to suddenly jump to 2200+ ATK on summon is concerning)
I own several commons where I have 3 unplayed copies of the same card, and I cant do anything with them
Afterwards you bring the cards to our point of sale stores
You have to build it correctly, but that can get you an unblockable giant creature or maybe a One with the Multiverse
In motion, these details are much more dynamic
