Verhey concluded the video stating that no matter how good a mechanic is, you have to look at how it impacts games from start to finish
This popular Commander finisher is a great dump for all that extra mana, and you can use Corrupt, Crypt Rats, and Consume Spirit in mono-black decks just as well
Thats useful in and of itself, and while we went out of our way not to include the Sanguine Bond + Exquisite Blood combo (you should have them both in your deck), having one of those effects on a Creature is useful
They mutate into the creature on top plus all abilities from under it.) Whenever this creature mutates, search your library for a basic land card, put it onto the battlefield tapped, then shuffle
Jor Kadeen, the Prevailer, maybe
My initial thought was that youd put nine of these in just about any creature-heavy deck with black in it, but unfortunately they seem to be much rarer than other uncommons, and even at the end of release weekend, buying nine of these will set you back almost $90
