WR - Prowess/Spells matter aggro
RG - Monsters/Ramp with Combo
GW - Tokens/Control

W - Go wide aggro package with exile removal, protection spells, midrange to control finishers. Wants to flood board, protect key threats, and remove opponents permanents to finish the game on its own terms.

R - Go fast aggro package with burn removal, board wipes, midrange and combo finishers. Main card draw/selection color of the shard, access to 3 stuffy dolls and boom boom board wipes for finishers, dragonstorm and cheaty ways to cast without being to on-rails/parasitic.

G - Ramp package with fight removal, midrange and ramp finishers. Ramps hard, has some combo potential but wants to slam fatty after fatty and overwhelm smaller boards quickly and definitively.
