Collectible Card Game Headquarters

Describe the Bug:
If you hit cancel so as not to sacrifice a permanent you are asked to 'select a card'.

Which card did behave improperly ?
Descent into Madness

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 ?
It should be 'Select a card to discard'.

Are any other cards possibly affected by this bug ?
-

Note: save is from a previous bug, just advance a few turns and it will crop up.

Also the first text could get an improvement now it asks "select target permanent" it would better if it said something like: "select target permanent you own to exile"
