Reach, basic landwalk

When Yuma enters the battlefield, it explores. (Reveal the top card of your library. Put that card into your hand if it’s a land. Otherwise, put a +1/+1 counter on this creature, then put the card back or put it into your graveyard.)

Yuma enters the battlefield with three Arrow counters on it.

Remove an Arrow counter from Yuma: Put a -1/-1 counter on target creature.
