I already got that far.
I was looking for an actual hint...
And another view of the other puzzle opponenet plays purify, you go poison. (Either both upped or unupped)
Krahhl's puzzle.
Fire: fire bolt
Aether: thunder bolt
water: ice bolt
Death: poison (most promising)
Darness: drain life.
And unfortunately the AI won't use pandemonium unless you have more creatures than him.
You have banned every possible way to get a creature, so spells and permanents are all that are left. (and your No creatures In Hand part includes teh 8th card, and mono-time won't lose it's creatures) He nightmares a creature is also banned, so I am stumped.
Weapons are the only "useful" permanents, the best being gavel/shortsword, unless the solution includes teh opponent doing something, in which case vampiric dagger.
Perhaps your Idea of animating weapon spamming to waste quanta...
But air fails in this case.
I guess you can fractal his creature, but spark dies, photon lives (unless you thunderbolt it and he also has a fire shield) and lacks damage, phase recluse also lives, and anything else is non-aether.
fire bolt > ice bolt in all cases.
Fire > drain life unless you need that health.
Cremation fails. 12 different quanta to waste, and you don't even have a target.
Thunder bolt seems best, but you can't play 6 in an 8 card hand unless you have 2 Qtowers, but that is also not allowed.
The opponent can never damage himself.
