I couldn't figure out why there was a heart at the end of this post. (lol)
Dude, cascading into Abrupt Decay is total BS.
I read all that dialogue in my head with Jace being played by that guy that played Peter on Heroes and Ral's dialogue by the guy who played Mark Sloan on Grey's Anatomy. I'm pretty sure both of those dudes could deliver the dialogue exactly as written.
Living End, Restore Balance? Also, Hypergenesis is banned because Cascade exists. Its not even just the brokenness of the mechanic. Its mindless 2 for 1s and the rate of return on a 3/2 haste is too high to also get to Cascade any 3 or less CMC spell that you get. You're basically getting a 3/2 for free on top of whatever the payment is for the spell you get. 3/2 haste isn't a bad return even if you turn over Thoughtseize or Bolt.
