mtg polymorph cards Morderkainen's X 3 (MTG Single Card) - collectibles - by owner - sale Maybe a little *too* convincing. Fantasy North - Polymorph -

No doubt players will look at this card and their first thoughts will jump to long-time staples such as Relic of Progenitus and Soul-Guide Lantern, both of which can exile entire graveyards while simultaneously giving you the ability to draw a card in the process, replacing what you lose in the transaction

Running Eldrazi Temple is a much more serious cost than simply playing Magic

Opponents will likely have some sort of enchantment- or artifact-based graveyard hate (such as Rest in Peace, Relic of Progenitus, or Grafdiggers Cage), so bringing in Natures Claim is a given

Each one has its unique perks, so find the one that works best for you depending on how many cards you are shipping at once

Mutilate is great but requires you to be heavily committed to Black or mono Black
