The Entmoot

Suspend 3—{g} (Rather than cast this card from
your hand, you may pay {g} and exile it with 3 time
counters on it. At the beginning of your upkeep,
remove a time counter. When the last is removed, cast
it without paying its mana cost.)
During your upkeep place X +1/+1 counters on
each creature you control. Where X is the
number of counters you removed from cards you
own in exile this turn.
