What does Kellan Joins Up do?
user
When Kellan Joins Up enters, you may exile a nonland card with mana value 3 or less from your hand. If you do, it becomes plotted. (You may cast it as a sorcery on a later turn without paying its mana cost.)\nWhenever a legendary creature you control enters, put a +1/+1 counter on each creature you control.
