A question of Troll Ascetic

[tysxych]

Player A controls Troll Ascetic and a Terror in hand. Player B uses Mindslaver to control A's next turn. Can B uses A's Terror to destroy A's Troll Ascetic?
Thanks!

The simple answer is "yes."

From the looks of the question though, it seems a bit of a misunderstanding about how mindslaver works lead to the confusion as to whether this was a legal play or not.  B is not actually using A's terror, or anything else of A's.  B is simply making all of A's decisions, instead of A doing it himself.  It is still A playing the terror, so A still controls it and Troll Ascetic is a legal target for it.  B just makes the decisions for A, the decision to play the terror, what to target with it, how to pay for it, etc.
