The Gauntlet

Protection from Blue
When The Gauntlet enters the battlefield, attach
it to target creature you control.
Equipped creature gets +2/+0 and gains
"{p/r}{t}: Deal 2 damage to target creature or planeswalker."
Whenever equipped creature dies, attach The Gauntlet to the last creature that dealt damage to
it this turn. At the beginning of their upkeep the player who controls equipped creature loses 1 life.
