Welcome to Smogon! Take a moment to read the Introduction to Smogon for a run-down on everything Smogon, and make sure you take some time to read the global rules.
Why is Baton Pass banned in practically every tier? I can't imagine it being abused by any Pokemon other than Smeargle, and even then it is completely shut down by common Taunt users such as Tapu Lele and Greninja.
Another counter would be Rapid Spin and Defog users such as Komala, Skuntank, and Archeops. Komala is a particularly good counter to Smeargle as it is immune to Spore and the paralysis from Nuzzle, and can remove hazards using Rapid Spin.
No matter where I look, I find that Marshadow is allowed in DOU. It is at the top of the viability rankings, not listed in the format's bans, and the only suspect test for it ended in a no-ban. However, it is not allowed in teams. Is this a mistake, or has it been banned and everything needs to...
My nickname comes from my fictional 4-dimensional world. I wanted it to sound scientific, "Quarti" is Latin for 4, and many places end with "ia".
Yes, that is Quartia pictured there:
