Collectible Card Game Headquarters

Describe the Bug:
1- Mercurial Pretender can copy opponents creatures (that you don't control).
2- It's effect card doesn't show as activeable - highlighted when it can be used and is empty of title & text. FIX: move title and text from effect slots to legacy ones I will report this to legacy forum as well.

Which card did behave improperly ?
Mercurial Pretender

Which update are you using?(date,name)Which type(Duel,Gauntlet,Sealed Deck)
Manalink 2015/3/25: Fate Reforged,duel

What exactly should be the correct behavior/interaction ?
1- Mercurial Pretender can't copy opponents creatures unless you control them.Can copy only creatures you control.
2- It's effect card doesn't show as activeable - highlighted when it can be used and is empty of title & text.

Are any other cards possibly affected by this bug ?

Fixed copying in f15fdb6. Couldn't repro lack of highlight.

Was fixed by you when fixing these

Works correctly, but could you change the prompt from 'select a creature' to 'select a creature you control'?
