Nut Collector

At the beginning of your upkeep, you may put
a 1/1 green Squirrel creature token into play
under your control.
Threshold — All Squirrel get +2/+2. (You have threshold as long as seven or more cards are in your graveyard.)
Avoid a scurry of Krosan Squirrels in the autumn.
Even the trees fear their hunger...
