You can go Voltron (and that's likely where most people will go), but you're in colors that support pillow fort, prison/stax, or even just plain stompy

The standout cards in terms of value include Aurelia's Vindicator, Anzrag the Quake-Mole, Vein Ripper, Trostani, Three Whispers, The Pride of Hull Clade, Vannifar, Evolved Enigma, Massacre Girl, and Rakdos, Patron of Chaos

As a mechanic I think it's fine, though it does require you to be either getting some good effects from the card itself or rebuying some pretty great abilities to be worth the tempo loss
