Flipping Out Champions of Kamigawa prerelease and opened a card that looked something like this: Today I'm going to explain what exactly these cards are and how they came into being
Its really only run in Jund and Abzan in Modern, and usually then as a 1-of in the sideboard
Chalice of the Void with one counter will not react to Suspending Rift Bolt (because it is a special action, not casting a spell), and Chalice with zero counters wont react to casting Rift Bolt, as its mana value is three, not zero
I also love this with The Stick (Isochron Scepter), or casting everything from your library with Future Sight
If you don't control any creatures with power 4 or greater when the ability resolves, the ability won't do anything
Your commander might decide on the common thread of your deck, but it should not be its pinnacle
