Uva, the Hidden Queen

At the beginning of your upkeep, you may put
an arrow counter on any number of creatures
you control.
Creatures you control have {t}: remove all arrow
counters from this creature and deal that much
damage to any target.
{x}{x}{g/w}: Up to X target lands you control
become 2/2 wolves with Indestructible until
end of your next turn turn. They're still lands.
