Gaslighter

Imprint -When Gaslighter comes into play,
you may have a target player reveal their hand.
If you do, choose a nonland card from it and
remove that card from the game.(The removed
card is imprinted on this artifact.)
Whenever a player plays a spell that shares a
color or converted mana cost with the imprinted
card, Gaslighter deals 2 damage to that player.
