They wouldn't be that bad in Duel Links. Probably not Tier 1, but I see them about at the same level as Aromage here, which isn't a terrible place to be.
Yeah, just like Metaphys, Aroma, Deskbot, Madolche, and all the "trash tier decks" that are just giving smart players huge win streaks against your generic meta decks.
It’s all about gameplan. U.A is garbaj in TCG and is also garbaj in here (relying on a broken Cyber Style, deck sucks after it got nerfed), because they have flawed gameplan. Metaphys too, isn’t very good because their gameplan isn’t good. Amazoness and SSA doesn’t have bad gameplan, that’s why they works
U.A. only works much more smoothly if they open with Midfielder, while Metaphys needs to be summoned by another Metaphys monster for their main effect to work. Metaphys Tyrant Dragon is just too slow. The easiest way to do it, is by using the in-theme low level monster we don't have yet in DL, Metaphys Decoy Dragon and Metaphys Ragnarok.
