mtg alpha booster box - Case - Alpha rare Headliner card signed by members of the Star Trek cast. Alpha Edition Booster Pack

Improvisation Capstone Read Improvisation Capstone closely and you'll see that it results in at least one free spell, and the catch is you get at least four mana's worth in case you exile Lightning Bolt, Curse of Opulence, and Underworld Breach, you could cast each of them

This card is a really great design

Access Maze on the other hand could turn out to be pretty sweet value

There are times where this will backfire, but I think the biggest advantage of this over Pyrostatic Pillar as a maindeck card is that you cant get locked under it by a bigger creature deck as easily because you can just chump block with it and go back to casting spells
