The List

Odyssey

At the beginning of your upkeep, you may put a 1/1 green Squirrel creature token into play.
Threshold All Squirrels get +2/+2. (You have threshold as long as seven or more cards are in your graveyard.)

Because damage remains marked on a creature until the damage is removed as the turn ends, nonlethal damage dealt to Squirrels may become lethal if the number of cards in your graveyard falls below seven.
