the thing is, you cant rely solely on UGs for you damage output (considering 3|2 and 6|2 isnt beefy by any means)
it face similar problem like the AM/Ls combo, at least traditional nympho can get around their weaknesses (mainly immaterial creature, if you go queen nymph route anyway) but your deck will just auto lose vs any reflecting shield
i'm not saying its terrilbe but maybe you need to include some other damage output and/or ways to counteract healing capabilities without completely dependant on UGs
