I think field of the dead is BROKEN. It has a very small opportunity cost and an insane payoff. It goes in any slow deck with good mana and essentially lets them totally invalidate most other late game grind options by giving you a lot of free tempo and resources. I think it scales to the power level of the format somewhat insofaras more fixing and especially fetch lands make the card much stronger but this card wasn’t banned from Standard, Historic, Pioneer and Modern just because it interacts well with scapeshift or primeval titan, you just freeroll it in late game decks and get crazy advantages for no real cost. It also has really polarizing play patterns where in slow mirrors the player with field is an overwhelming favorite and being a land, it’s often quite hard to interact with, especially in lower power formats that aren’t running mana screw lands.
