Sapling of Colfenor

Indestructible

Whenever Sapling of Colfenor attacks, reveal
the top card of your library. If it's a creature
card, you gain life equal to that card's toughness, lose life equal to its power, then put
it into your hand.

The Sapling of Colfenor, eldest of the greenborn, could not be burned, broken, or bent, for his roots drank deep of the world’s first light.
