Flying Ward 2 (Whenever this creature becomes the target of a spell or ability an opponent controls, counter it unless that player pays 2.) 2: Put target card from a graveyard on the bottom of its owner's library.

When this creature enters, 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 this creature, then put the card back or put it into your graveyard.)

At the beginning of combat on your turn, this creature explores. Then you may have it become a copy of another creature you control until end of turn. (To have this creature explore, 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 this creature, then put the card back or put it into your graveyard.)

When this artifact enters, distribute three +1/+1 counters among one, two, or three target creatures you control. Craft with creature 5GG (5GG, Exile this artifact, Exile a creature you control or a creature card from your graveyard: Return this card transformed under its owner's control. Craft only as a sorcery.)

Vigilance Whenever this creature enters or attacks, create a Map token. (It's an artifact with "1, T, Sacrifice this token: Target creature you control explores. Activate only as a sorcery.")

Whenever Kellan attacks, reveal the top card of your library. If it's a creature card with mana value 3 or less, put it into your hand. Otherwise, you may put it into your graveyard.

T: Add C. 2: This land becomes a 3/3 Elemental creature until end of turn. It's still a Cave land. Activate only if the number of other Caves you control plus the number of Cave cards in your graveyard is three or greater.

Flying, lifelink At the beginning of your end step, if you descended this turn, scry 1. (You descended if a permanent card was put into your graveyard from anywhere.)
