Ran, Thoughtcarver

Hexproof, Homing
If Ran would deal combat damage to an
opponent this turn, you may prevent that
damage and instead, look at the top X cards of their library where X is the amount of damage that would be dealt and you may exile any number of cards with converted mana cost equal to or less than Ran's power.
Ran has +X/+0 where X is the number of cards put in exile with Ran's effect.
