all the number cards in yugioh zexal Complete Custom Deck for Yu-Gi-Oh! Yu-Gi-Oh! Wiki - Number S0:

I kind of hoped this would find its way into Standard when The Brothers War (BRO) released, given its relevance in regards to that set, but alas

It doesnt untap during its controllers next untap step

So yeah, Eeries restricted to a small subset of decks, but this is wild mass reanimation for these colors, and its mostly strategy-agnostic unless youre running one of those super-popular Abzan spellslinger decks

What sets Rakdos Sacrifice apart from other decks using this engine though is the inclusion of [c]Mayhem Devil[/c]

It has an interesting restriction on when it can be cast for free, but not nearly prohibitive enough to make this card bad
