I like him in Tower shells...and with Weapon Enthusiast...or in Colossus decks...or with Tracker/Bishops...and I love him with Hidden Stockpile

So I put him in my Jund Reanimator deck and he's really good (if you get him in hand). You can intentionally pitch him to the graveyard and cheat him out 1-2 turns early. If your opponent has cards in hand he's brutal for them on your end step and plus they have to deal with a 5/5 flyer. The second ability is worthless to me in my deck but he's still worth having in there.

Has anyone got a good Rakdos Improvise deck that can cheat out him and the dragon consistently on T3/4 and is not trash?

I was struggling with this deck mainly because we only have four 0 cost artifacts.

So far I only play it in my Grixis Control deck. Seems like a good card to me, casting this for 4-5, but maybe I'm biased (since it dies easily). But if they are tapped out it will be a 2for1 at least.
