Bugs with take control (Emrakul, the Promised End)

These issues all occur in matches on the local server against a computer opponent.
1. [ ] When an opponent is controlled, there is no limit on the number of lands you can play for them.
2. [x] After the control effect ends, the "switch hands" button does not disappear, allowing you to continuously view your opponent's hand.
3. [ ] When a controlled opponent uses a Fetchland, the following error report appears:Error type: SERVER - game error
