removing cards from the graveyard tends to correlate to grindy games that benefit from a creature you can chuck into play that slowly accrues advantage over a long game, especially if you throw in some cards that care about zombies or tokens
If this card is sent to the graveyard or banished, you can add a Void Spell/Trap directly from your deck to your hand
