If my opponent has a creature with the "Claws of Valakut" enchantment on it (Enchanted creature gets +1/+0 for each Mountain you control and has first strike), and I cast "mind control" to take control of that creature:
1) Does the enchantment also come under my control? If not, what happens to it?
2) If I get the enchantment as well, does the "you" on the card refer to me or still refer to my opponent? In other words, does the creature still get the bonus based off of the mountains my opponent owns or does it depend on the ones (if any) I own?
