Whenever this creature deals combat damage to a player or planeswalker, draw a card. Discard a card: Put a +1/+1 counter on this creature. Exile three cards from your graveyard: This creature gains flying until end of turn.

Menace, lifelink, indestructible Ketramose can't attack or block unless there are seven or more cards in exile. Whenever one or more cards are put into exile from graveyards and/or the battlefield during your turn, you draw a card and lose 1 life.

If this card is in your opening hand and you're not the starting player, you may begin the game with Gemstone Caverns on the battlefield with a luck counter on it. If you do, exile a card from your hand. {T}: Add {C}. If Gemstone Caverns has a luck counter on it, instead add one mana of any color.
