Malthia, Roaming Feeder

Whenever a creature explores, create a blue 1/1
Fish token with "This creature can't be blocked."
{1}{g}: Exile target card from a graveyard. Malthia 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.)
{u}: Target creature you don't control explores.
