Agent Venom (Flash Thompson)

Vigilance, Lifelink
Symbiotic Armament: Agent Venom gets +2/+2 for each Equipment attached to it. You may sacrifice an Equipment to give Agent Venom reach until end of turn.
Tactical Retrieval: Whenever Agent Venom deals damage to an opponent, search your library for an artifact card with mana value equal to or less than the amount of life you gained this turn, reveal it, and put it into your hand. Then shuffle your library.
