I'm still trying to think out this TU problem.
I still think this is not a real problem...
Now the questions...
BTW, what about skills? I think "mixed up" should be a one-turn passive ability, so that it can't be Lobo'd, and it isn't just mass Lobo...
I suppose TU'd mixed up creatures get un-mixed up after attacking.
I mean, your enemy has a 5|3 Frog, you use Mix Up, now it's 3|5. You have excess 
quanta so you TU that useless frog, now you have a 3|5 frog, but it will go back to 5|3 next turn??
Also, do the un-mix up happen right after the attack? I think it should.
I believe your questions have already been answered in the main topic.
Oh, ya lol. Anyways, when you say "after attacking" you mean RIGHT after the attack? I guess yes, but just in case...
And I forgot about this question too.
I wonder what would happen when an AM'd creature gets mixed up, or if an already mixed up creature gets AM'd... I suppose it dies once its hp is negative. Also, what about 0 atk creatures? They die when mixed up or after attacking?
I want to point out that I'm asking if there is a difference between a mixed up creature that had 0 attack and another one with negative attack (there is no way a creature can have negative attack, so a mixed up creature with negative attack either dies or gets 0 hp for some weird reason, and weird reasons are a bad choice).
