Hel Rounds

Can only be equipped to a card equipped with a Slugthrower or Heavy Weapon card.
When the equipped card defends or when it is defended against, target the opponent's card
involved in the battle if it survived and place a
-1/-1 counter on that card. At the beginning of
each player's turn, place another -1/-1 counter on
that card. That card dies when its defense value becomes 0, then spawn one 1/1 Vong Parasite
with Deadly Strike Token on your field.
