Full Moon

Suspend 3—{u}{u}{u}(Rather than cast this card from your hand, pay {u}{u}{u} and exile it with four 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.)
This spell can't be countered.
All waterbenders get +5/+5 until the end of turn.
