I would like to challenge this with my friend's Legacy Mardu deck, it is over powered and this might be fast enough to stop it.

It is fast, but needs something for the late game. Maybe Endless One. Just an idea?

@xJonahSlayerx this deck usually wins in MAX 5 turns, usually 4. So there really isnt a late game.

There is a chance for the game to go late if either my creatures are killed or I assume a defensive role from the start and use my burn to contain the opponent's creatures. In the first case, Traverse the Ulvenwald for Bedlam Reveler typically provides enough reach to win. In the second case, Tarmogoyfs are strong enough to win after the board is clear.
