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.
nah it's not anything over-the-top spectacular, but it's rly fun to mess with. use resttalk cm with a stab of choice (hyper voice hurts, dazzling gleam has better mono coverage) and mons to lure / weaken steel-types, dragalge actually does that job spectacularly
worth noting that u can use it to pivot during early-to-mid game with the recovery from rest + regenerator. you can also set up on dragalge if it switches when you get to +1 if you dont' mega evolve. that's all i think
don't think so. make sure u don't make a super drapion-weak team like i did tho (cause i thought audino was enuff to cover all of the dark-types, protip: drapion demolishes it).
you're likely to end up with something very close to a stall team, so pay attention to that as well
