Sephira, Celestial Arbiter

Natures insight -Whenever a creature enters the battlefield under your control, you may look at the top card of your library. If it’s a nonland card, you may put it into your hand.

Whenever you cast an instant or sorcery spell, if you control three or more creatures, draw a card, then discard a card.

At the beginning of your end step, if you control five or more creatures, create a 4/4 green Elemental creature token with trample.
