My favorite three decks: Blue-Red 4-drop spells : This is the base archetype for UR, and is supported quite well Grixis Control: As the name suggests, this is basically just all the good Grixis removal and card draw combined, with some lands for good measure
These are often free events, so visit your local game store and ask
Think Wilhelt, the Rotcleaver and its many zombies
Ornithopter of Paradise As an artifact creature with little toughness, Ornithopter of Paradise is quite fragile, but giving any deck that chance to play a mana dork that fixes all their colors shouldnt be overlooked
They are brilliant in Commander too as yours in a 40-life format too
These cards can also be useful to get your characters healthy again if you decide to use Four Dozen Eggs to defend the board
