Mila, Crafty Companion // Lukka, Wayward Bonder

{1}{W}{W}Legendary Creature — Fox // Legendary Planeswalker — Lukka

Whenever an opponent attacks one or more planeswalkers you control, put a loyalty counter on each planeswalker you control.

Whenever a permanent you control becomes the target of a spell or ability an opponent controls, you may draw a card.

+1: You may discard a card. If you do, draw a card. If a creature card was discarded this way, draw two cards instead.

−2: Return target creature card from your graveyard to the battlefield. It gains haste. Exile it at the beginning of your next upkeep.

−7: You get an emblem with "Whenever a creature you control enters, it deals damage equal to its power to any target."

When Mila’s first ability resolves, you will put a loyalty counter on all planeswalkers you control, even ones that aren’t being attacked. (2021-04-16)
Mila’s second ability will resolve before the spell or ability that caused it to trigger. (2021-04-16)
Mila’s first ability triggers only once no matter how many creatures are attacking or how many planeswalkers are being attacked. (2021-04-16)
