Mila, Crafty Companion

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 and opponent controls, you may draw a card. // Lukka, Wayward Bonder [+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.”
