Well testing rainbow nymphs +ups against aether went surprisingly well:
Devtal: 5-0
WiseDragonDims: 4-3 (was 2-3, it's RNG, all depends on getting the quanta for pulvy. Only included one win from Reflect Shield, afterwards played around it. never play reflect shield until you have to to win a game.)
DimsPoison: 5-0
BoneBolt: 2 -3
Fast monos will smash it, especially with lobo, but I think the above decks are more likely, especially devtal.
It's not a perfect solution, but i can't see a more elegant solution. I am very very happy to change it if someone comes up with a better idea
