Im a big fan of these decks that use Brainstorm, Deathrite Shaman, and fetchlands
There is also the silver border Krarks Other Thumb, which you could rule zero in, and because its colorless, you can put it in all your decks
There's also a ton of ramp in this deck, but I'm going to strike that down as a positive for now, especially given the mana costs for activating the abilities of the Fantastic Four cards, which could be awkward if you're not drawing the lands you need early in the game
3/4 Ditto - Ditto V is rotate, this is basically the weaker version of it, only for non-Rule Box ones
