: Looks like it needs another top-end card and/or better enter the battlefield effects. Sun Titan
: There might be too many counterspells, will replace with draw or other disruption effects after testing.
: Better overall creature quality, not sure if Rogues are that strong right now. It could potentially be better to move away from Rogues and toward Assassins with Rooftop Bypass, Ezio, Blade of Vengeance, and Achilles Davenport.
: Vampires on the red side might feel really mismatched, Madness and Spectacle payoffs aren't the best.
/: Dinosaurs could be too tall for other colors to deal with, so think of other ways to tune stats down but still keep the power level there.
