Collectible Card Game Headquarters

Describe the Bug:
I used Tezzeret the Seeker ultimate ability having on board 2 Rod of Ruin.I then attack with them and when blocked I used my 2 Berserk to boost them.As soon as I target the first animated Rod of Ruin I get the error "bla,bla...
Addtype error:no room in CT to add another type"

If you click ok on the error then the targeted animated Rod of Ruin will not show p/t

But then on damage step after the addtype error shows again it will inflict damage but not take damage.
I know there is a limitation on how many types can be hold(per turn?)but I don't if there is a bug that makes this appear sooner than it has to.
Which card did behave improperly ?
Tezzeret the Seeker

Which update are you using?(date,name)Which type(Duel,Gauntlet,Sealed Deck)
Manalink 2014/12/20: Commanding 2014 Urzas,duel

What exactly should be the correct behavior/interaction ?


Are any other cards possibly affected by this bug ?
-

Just to add, I also tried casting the Berserk's as soon as attackers were declared (before blockers were) and they worked fine. As soon as blockers were declared is when the issues started. P/T went away, damage wasn't done.

The probably culprit is Berserk code.
I've redone it in 162bea0

Exact same behavior, no change.

Edit: immediately after testing this I tested Wrap in Flames and received the same no more room for cards error (but the card ultimately worked), so Berserk probably has nothing to do with it.

Berserk code was still buggy, it's fixed in 21a4d4d
I've a tested a bit and the bad interaction with animated artifact is gone.
