The cost of play is low, but the maintenance is limited due to limitations, and there is no function to prevent test failure, so it is a card that should be used purely with the aim of exceeding success
All this sacrificing means youll also probably want some Recursion, too, so consider adding cards like Black/Green cards that will help you get things back from your Graveyard such as Phyrexian Reclamation, Greenwarden of Murasa, Reclaim, Regrowth or Skeleton Shard
Of course, I want to reanimate Phyrexian Dreadnought on the regular, which requires a contingency plan
A 6/6 for 6 mana is pretty standard, but it also gives you an immediate buff to one of your other creatures
Short answer: Yes, if youre in it for the art and the long game
