Altrazian Mech

Captain - This card must be your commander. Before the game starts, chose a color. This card's color identity is also that of the chosen color.

Eminence - Vehicles in your hand can be played face-down as Wastes with: "{2}, {t}: Add this card to its owner's hand." (This counts as your one land drop per turn)

If a creature of the chosen color crew Altrazian Mech, you get a Poison Counter. Altrazian Mech gets +1/+1 for each poison counters on each player.
