Intrepid Roil Surveyor

When this card enters the field, it explores.
(Reveal the top card of your deck. Put that card into
your hand if it's a Biome. Otherwise, put a +1/+1
counter on this card, then put the revealed card back
or into your Netherworld.)
Whenever a Creature or Biome card enters the
field under your control, target card you control explores. If this ability triggers three times during
your turn, search your deck for a Planet card and
add it to your hand. Shuffle after.
