Collectible Card Game Headquarters

Describe the Bug:
Polis Crusher can't be targetted by instants, sorceries, abilities or equipment.

I guess it has been coded that way intentionally, because it's hard or impossible to give protection from enchantments exclusively, but in that case it would be more balanced if it could be targetted by everything, so the opponent can kill it with spells in exchange for the player being able to pump/equip it.

Which card did behave improperly ?
Polis Crusher

Which update are you using?(date,name)Which type(Duel,Gauntlet,Sealed Deck)
CIA v2, Duel

What exactly should be the correct behavior/interaction ?
Polis Crusher can be targetted by abilities and all spell types except for enchantments.

Are any other cards possibly affected by this bug ?

Any of the devs want to chime in on the limits of protection approximation?

Won't be fixed properly until I find time to get generalized protection done. Probably the patch after this coming one; most of the prerequisites have been completed as part of other stuff. This is the root bug for it.

In the meantime, we could remove shroud, but I don't see much point either way.

Fixed by drool66 in commit c04a46f.
