The newish Ancient Gear structure deck continue to be a pain to deal with in Duel Links if you have a Cosmic Cyclone to banish Geartown (or if they don't brick).  As ridiculous as U.A.'s damage potential can be for Slugger with backrow/monster effect disabling, it takes more setup and doesn't let you crap a 3k beater with a similar effect onto the field by destroying a field or continuous spell (which usually gets rid of one of your backrow because of the backrow destruction card in the structure deck). Not to mention, Reactor Dragon can usually summon another of itself at the end of the turn because of IT's destruction effect.

I'll take them over a third  Slvan/Fur-Hire invasion  or dealing with un-nerfed Cyber Angels (from what I've heard), but they are getting annoying, especially if they are packing Pulse Mines.
