power nine cards mtg 9 Set - Proxy Beta The Power Nine | MAGIC:

If youre playing Commander, the Comply portion can prevent them from casting their commander until the next turn if its still in the command zone

Cloud, Midgar Mercenary Cloud, Midgar Mercenary is all about equipment

Legendary Creature - Dragon Bird Stormbreath Dragon Flying, haste, protection from white : Monstrosity 3

Still, this card is not perfect: Its difficult to build a deck that can make Murktide shine entirely, apart from UR Murk: cheap spells, counterspells and removals are usually a mix only playable in Izzet decks

Im not targeting it in a dedicated way

Since those cards are exiled and you will eventually, hopefully, cast some of them, you might want to include some cast from exile synergies with cards like Flaming Tyrannosaurus
