Malulu Summoner

When this creature enters, reveal cards from
the top of your library until you reveal a creature with mana value 4 or less. Put that creature onto the battlefield. Put the rest on the bottom of your library in a random order.

Whenever another creature enters, reveal the
top card of your library. If it’s a land card, put it onto the battlefield. Otherwise, put it into your hand. This ability triggers only twice each turn.
