Mag

{w/u}{t}: Tap target creature. Then, put a 0/1 colorless Shard creature token onto the battlefield tapped.
Sacrifice all Shard tokens: Deal X damage to target creature or player, where X is equal to the number of Shard tokens sacrificed.
This is Mag, a force to be reckoned with. Mag is a team player, Tenno, and a worthy addition to any squad.
