Collectible Card Game Headquarters

Describe the Bug:
When Clone resolves, it is put into its controller's graveyard before its controller is prompted to choose a creature to copy. Choosing a creature that way results in the client crashing.

Which card did behave improperly ?
Clone

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

What exactly should be the correct behavior/interaction ?
When Clone resolves, its controller is prompted to choose a creature to copy. Choosing a creature that way results in Clone being put onto the battlefield as a copy of the chosen creature.

Are any other cards possibly affected by this bug ?
Also affects Phantasmal Image (see savegame), Clever Impersonator and Dack's Duplicate.
Very likely affects other creatures that share code with Clone.
Does not affect Sakashima the Impostor.

I knew I had seen Clone variants behave like this before. Bug is identical to the one found in previous Manalink versions, see Dack's Duplicate report and Clever Impersonator report.

Fixed robustly in bce5e5c for all such cards that go through the proper interface functions instead of cut-paste-modify-pray, and made Clever Impersonator do so in 630ca7b.
