Describe the Bug:
When Puca's Mischief's triggered ability resolves, control of the targeted permanents is not exchanged.

Which card did behave improperly ?
Puca's Mischief

Which update are you using?(date,name)Which type(Duel,Gauntlet,Sealed Deck)
CoRM15 mini4, duel

What exactly should be the correct behavior/interaction ?
When Puca's Mischief's triggered ability resolves, control of the targeted permanents is exchanged.

Are any other cards possibly affected by this bug ?

Code fixed & greatly improved in dfeee8e

Works great, but could the first prompt be 'select target permanent you control' instead of 'select target permanent'?

Improved prompt in ee4c53f

No help text when triggered (there is help text when targeting opp's perm).
