Fun Power Up Brawl deck

This is an all Marvel (MSH and MSC) Brawl deck featuring Karolina Dean, Runaway. She makes WUBRG for free at the beginning of your main phase. It can't be used for casting cards from your hand, but anything else is fair game. Casting cards from exile? Check. Activated abilities? Check. POWERUP? Big check.

Since it's WUBRG you need a lot of dual lands, and Basic Landcycling can fix you up also.

The primary playstyle is to drop Karolina on turn 4 and then explode on turn 5. Want an 8/8 flying Wonder Man on turn 5? You can do that! Want to drop Thanos and Snap Squirrel Girl and her whole army? You can do that!
