Illumise

Flash, flying.
Insect spells you cast have convoke and cost {g}{g} less to cast.
Whenever an Insect enters the battlefield under your control, 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 that creature, then put the card back
or put it into your graveyard.)
