Victoria Serpentes

Ghost Strike - Victoria Serpentes has Lifelink as
long as she's attacking. Whenever Victoria deals combat damage to a creature, tap that creature and put a stun counter on it. (If a permanent with a stun counter on it would become untapped, remove a stun counter from it instead)

Mutagen - Pay 3 life: Put two +1/+1 counters on Victoria Serpentes. Activate this ability only as a sorcery and only once per turn.
