Lyla, Holographic Assistant

When this creature enters, you gain 2 life.

Creatures you control get +1/+1. Whenever you attack with one or more legendary creatures, you gain that much life.

Whenever this creature attacks, it gets +1/+0 until end of turn for each other attacking creature.

Vigilance (Attacking doesn't cause this creature to tap.) Whenever you gain life, put a +1/+1 counter on MJ.

Flying (This creature can't be blocked except by creatures with flying or reach.) Whenever you gain life, put a +1/+1 counter on target creature you control. It gains indestructible until end of turn. (Damage and effects that say "destroy" don't destroy it.)

When this creature enters, tap target creature an opponent controls and put a stun counter on it. (If a permanent with a stun counter would become untapped, remove one from it instead.)

Enchant creature When this Aura enters, draw two cards. Enchanted creature gets +2/+0 and has flying. (It can't be blocked except by creatures with flying or reach.)

When Spider-Man 2099 enters, return up to one target creature to its owner's hand. Whenever one or more creatures you control deal combat damage to a player, draw a card.
