Oko, Lord of the Fae

Creatures can't attack planeswalkers you control unless their controller pays for each of those creatures.

: Up to one target artifact or creature loses all abilities until your next turn.

: Create a 2/2 white Ox creature token.

: You get an emblem with "At the beginning of your upkeep, conjure a random planeswalker card into exile. You may cast that card this turn without paying its mana cost."
