Outlast

MTG Mechanic

The Abzan are all about endurance, and nothing prepares you for a long game better than growing your creatures over time. You can activate an outlast ability during your main phase if the stack is empty—otherwise known as any time you could cast a sorcery. Outlast abilities include the tap symbol, so a creature's outlast ability can't be activated unless that creature has been under your control continuously since the start of the turn (unless it has haste). When an outlast ability resolves, put a +1/+1 counter on the creature.
