It's good that these teams have more than a weakness or two for a variety of responses, but I do feel a line should be drawn somewhere.
This team has zero countermeasures to all sorts of birdspam and fishspam strategies; in particular, if you mispredict against a Fletchling, Drifloon, Corphish, or Tirtouga, the game just ends. It cannot switch into Porygon, Gastly, or either variant of Abra, and if Gastly / Abra gets up a Substitute against a predicted Protect, the game just ends. Its Carvanha + Gothita check is its own Carvanha; its Ground check is also Carvanha; its Fight check is LO Gastly; and its Timburr + Pursuit check is clicking X.
I think the best choice here would be the X button.
@ below: If Fletchling or Tirtouga or whatever is paired with Memento, that's an autolose, but even outside of that, it becomes incredibly risky to send your win condition in before Fletchling, Tirtouga etc. has been taken out because if they're sent in to revenge-kill, say, Torchic, you either lose your win condition (and probably lose the game) or you switch out and potentially have them set up (and lose the game).
I understand that Hyper Offense teams don't need to carry a switch-in to everything. They do need half-decent countermeasures against the top threats in the metagame.
I'd be willing to submit teams but my point is that it's harder to keep out joke nominations if the team is bad to begin with
