Animated Eternity

No idea.

Are you sure it was an AI and not PvP?
No AI3 and no FG has a deck with eternity & flying/animate weapon. It might be AI1 or AI2 but the chances are actually quite low IMO.
If it was in PvP, it's a typical desync problem, see "known bugs" sticky thread.

I only rarely play PvP so I know it was an AI. 

I'm in the process of upgrading cards to build a specific deck so, if I left myself short after upgrading a card, I may have played a L1 or L2 to get enough coin to play a L3 again, though I try not to leave myself that short.

When fighting an AI that animated eternity the resulting creature was unable to be targeted & was not affected by global effects (fire storm/thunder storm storm are the ones I tried in addition to trying to eat it with an Oty)

However when I animated an eternity it was affected by everything the AI threw at me that could normally affect creatures.

Anyone else see this behavior?  Addmittedly I've only seen an AI animate eternity once, but that time it was seriously annoying as I couldn't get rid of it and it kept putting otys back in my deck.
