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 could not be felled by blade or blight, for he was planted in the memory of the world itself.
