Emrakul, the Promised End was banned from the Standard format of its time and is one of the most powerful Eldrazi in the game
SWORD OF FORGE AND FRONTIER The other new Sword fares better than the March of the Machine offering, but not by as much as youd think
Provided there's not a combo incoming, it creates an impactful board state, and in the case of a board wipe, you just play out the cards in your hand you've been holding onto instead (or keep on making Pegasi if they don't manage to remove Sacred MesaSacred Mesa)
The first effect is important because the cards you cast can be countered, but not when you have Chimil out
The main reason I think this Minotaur kill is remotely close to reasonable is that Deathbellow War Cry is one set removed from Irencrag Feat
From my experience, Minds Aglow will draw you about 1-2 cards per player but depending on how quickly the board is established, its usefulness can drop off sharply
