Mila, Crafty Companion // Lukka, Wayward Bonder

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."
