[+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 enters the battlefield under your control, it deals damage equal to its power to any target."
Mila’s first ability triggers only once no matter how many creatures are attacking or how many planeswalkers are being attacked.
Mila’s second ability will resolve before the spell or ability that caused it to trigger.
When Mila’s first ability resolves, you will put a loyalty counter on all planeswalkers you control, even ones that aren’t being attacked.
