Collectible Card Game Headquarters

Describe the Bug:
Clone s of 0/0 creatures with +1/+1 counter when they enter the battlefield sometimes die immediately. Looks like this fails for everything except modular creatures. Must be implemented differently...

In testing a Kalonian Hydra bug on clones, I realized that I could not get a Clone of Kalonian Hydra to stay on the battlefield. They all die before they get their 4 +1/+1 counters. Even with multiple Grand Architect s in play, Clone, Phantasmal Image, and Phyrexian Metamorph all die immediately.

Testing with other 0/0 creatures yields varied results:

- Modular creatures can be cloned correctly (Arcbound Worker, Arcbound Overseer)
- Graft creatures can NOT be cloned correctly (Aquastrand Spider, Cytoplast Manipulator)
- Clockwork creatures can NOT be cloned correctly (Clockwork Beetle, Clockwork Dragon)
- Karstoderm, Anthroplasm can NOT be
- Ghave, Guru of Spores and Marath, Will of the Wild can NOT be (doesn't even trigger the legend rule)

BONUS:
- Crovax the Cursed actually does not work even by himself so I can't test (A separate bug but I'll make another thread).


Which card did behave improperly ?
Non-modular 0/0 creatures with +1/+1 counters

Which update are you using?(date,name)Which type(Duel,Gauntlet,Sealed Deck)
CIA v2 Jan 2014

What exactly should be the correct behavior/interaction ?
Cloned, and possibly trigger legend rule.

Are any other cards possibly affected by this bug ?
See above.

A cloned Kalonian Hydra doesn't get any +1/+1 counters.

Currently working for everything listed (both cloners and clonees) except for Marath, Will of the Wild. That one's problematic in that it only stores the amount of mana paid to cast it if it's already Marath, Will of the Wild as you're casting it; there isn't any easy way to retrieve the amount or colors of mana spent on a given spell.

Well, this bug sees fixed in dev, so consider it fixed until further notice.

As of CoRM15 mini2, Metamorph, Clone, Phantasmal Image, Sakashima and other clone variants work as intended when cloning 0/0 creatures that enter the battlefield with counters.
