Leg-Hugger Asta

Enchant creature
Attached permanent has -1/-1. Any +1/+1
counters placed on this card will increase its
effect. If attached creature is removed from the battlefield Leg-Hugger Asta can freely attach to a target creature.
When Leg-Hugger Asta reattaches to a new target discards all +1/+1 counters.
Leg-Hugger Asta must always be attached to a creature, if there is an available creature.
