MTGNexus

This game is the inverse of The Commander's Tools Game. You must make a commander card (legendary creature, or other legendary with "this can be your commander") whose deck could make good use of the card suggested by the previous poster. Naturally, the legend must be able to fit that card in their color identity. Then, suggest a new card.
