Collectible Card Game Headquarters

Describe the Bug:
Gather Specimens besides these problems mentioned here:
viewtopic.php?f=86&t=12357&p=136465&hilit=Gather+Specimens#p136465
Now:
1- if Gather Specimens is played on stack in response to a creature being cast the creature doesn't enter on caster's battlefield.I don't know if it works at all for human as when not played as a response on stack AI never casts a creature(correctly).For AI sometimes it worked when already on battlefield the legacy effect.
2- It doesn't work for tokens or creatures put on the battlefield whatsoever.

Which card did behave improperly ?
Gather Specimens

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 ?
1- Gather Specimens works when played in response to spell on stack.
2- Gather Specimens works for any creature or token put on the battlefield by spell/triggered,activated ability/as a spells cost or whatever other reason.

Are any other cards possibly affected by this bug ?
-

Changed implementation again in fcce8ef
Now Gather Specimens works like a counterspell, so it can "steal" creatures on stack.
Then, it will create a legacy card that do the same thing AND steal tokens / creatures putted directly on BF (but you won't get CIP effects from them).
