Cahara, Desperate Plunderer

Equipped Creatures you control cannot be blocked
Whenever Cahara deals damage to an opponent,
look at the top 3 cards of your library, you may put
an artifact card with mana value X or less from
among them onto the battlefield tapped, where X
is the damage dealt.
Whenever you equip a card to Cahara, you create a treasure token, this ability triggers once per turn.
