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
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
Triggering a Disenchant whenever any creature enters under your control is ridiculous, especially if you happen to be making a ton of tokens
Implement of Combustion If you want to unlock damage-based synergies like those required to turn on spectacle or bloodthirst, Implement of Combustion is playable
While there are many, many types of Magic players, each with their own correct way to have fun, I have strong faith that players like drawing cards, gaining life, and making their opponents lose life
