White I wrote the other week about how great the white cards in the set are, and so well start as we mean to go on with an absolute belter
This includes spells that target a single creature
So when you actually cast Emrakul it is absolutely the best at winning the game as it comes with a free Time Walk

In limited environments, Medicant Core's max speed ability will allow you to duplicate big, expensive artifact bombs like gearhulks for practically nothing, but in unlimited formats like Commander, it can get really wild, duplicating mana rocks and game-bending cards from thirty years of Magic sets
While i take your point about sideboard specific cards i would class the blasts and disenchant very differently - one is a occasion maindeck card with very wide sideboarding potential while the other is very obviously a sideboard only colour hoser
