Retreat

 is an ability in Nightbanes. It is an active ability, which means it will only activate once the creature has a full bloodlust counter.  For a list of all Cards with this ability, click here! 

Variations
can appear as certain activation, or with a chance to activate. It will always activate at the end of your turn.

Strategy
Most creatures with this ability have some kind of Inflict Damage ability and are often quite fragile, so they do well far away from your opponent's active Creatures!
