Veyl, the Lone Wolf Assassin

Weaponmaster's Reflex - (1): Equip a Legendary Weapon from your hand to Veyl. If you do, return any equipped weapon to your hand. Activate only once per turn.

Lone Warrior’s Precision — As long as Veyl is the only creature you control, he has hexproof and deathtouch.

Ghost Step — Whenever Veyl becomes equipped, he gains unblockable until end of turn.

Whenever Veyl deals combat damage to a player, you may destroy target tapped creature that player controls.
