Enter The Discoveries

At the beginning of your upkeep, target creature explorers. (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 the creature, then put the card back or put it into your graveyard.)
Delirium - You may play an additional on each of your turns as long as you have four or more card types among cards in your graveyard.
