Well, I have not touched the deck for ages because school has started again and I'm quite busy and so on... RL and so on... though I am still convinced that RL doesn't exist, there is just AFK.
Whatever, I never had problems with Faerie decks or Blue Fish decks. You can actually out.control them both via Counterbalance. There are just a few cards to keep off the table. I am only a bit afraid of Merfolk. And I have to admit UGw Threshold loses to such random trash.
But I think it's also possible to play David Caplan's UGr Threshold in your metagame, Burnspells can win you games against Landstill, as well as well-timed Wastelands and Stifles.
REBs help against your fishy problems...
Against the above stated decks, you could actually play both DerF's and my UGw variant well as the UGr variant of goobafish, but since I am convinced that UGw is the most versatile variant of both. Against Landstill, you have useful tools like Gadock Teeg, Needles and the Counterbalance lock.
I'd also say that it is a bit more consistent as UGr is quite reliant on tempogaming. If a the cards all come from the top in the wrong timing, things get obsoleted withing a few turns quite quickly. Needs a lot of playtesting to figure out how to time the cards well (I also have some trouble with that from time to time).
