Calm mind on Azam is uh... kinda pointless in game. I've personally never had more than a 10 turn battle in game, since Level > all, so I don't give a **** about boosting (go go sweeper everything).
Now in competitive battling, there's a use for CM zam... against, maybe, teams without a special sponge. Now, rare as they are, they do exist, so go nuts with it and pray, because more often than not will you find a team that has at least 1 sponge that will completely dominate a CM zam.
Or you can just end up getting owned by a physical on a switchin, but of course you wouldn't be doing that either.
Also, as pointed out, TTar is godly OU'd in the metagame, so basing a moveset off the assumption that you'd prolly not run into at least one dark type isn't gonna work too well.
And finally, Tpunch is quite possibly the best way to go on a CM zam. Don't see the point of trick in game anyways, no one has like items >_>
