#6 - Captain Howler, Sea ScourgeCaptain Howler, Sea Scourge This Shark Pirate is formidable, consistent, and has a fun play pattern
Triggering a Disenchant whenever any creature enters under your control is ridiculous, especially if you happen to be making a ton of tokens
Making that happen is something black does extremely well
I dont expect any of these to matter in competitive Constructed formats, so they really come down to how useful they are in Draft, Sealed, and EDH
The Replenish deck could sit back, lose card advantage turn after turn with Attunement, and still come out and win at its leisure as Parallax Wave, Opalescence, Seal of Cleansing, and other enchantments all entered play at the same time
