Planeswalkers

MTG Mechanic

Planeswalkers are cast as spells, just like any other nonland cards. There's a number in the lower-right corner of each planeswalker card. That's its loyalty. It enters with that many loyalty counters on it, whether you cast the planeswalker as a spell or if it entered some other way. It needs those loyalty counters to stay by your side. If a planeswalker ever has no loyalty counters on it, it's put into the graveyard.
