I've heard the best ingame Ttar is probably the DDtar... But ingame would it be useful to use taunt... Or would it be best to use something lke Aerial Ace? or Brick Break?
Thunder Wave might work as a secondary option to Crunch on that set, but I don't recommend using it. It's only useful as the InGame replacement for Taunt on a DDing Gyarados.
ingame roaring is rare but for the fourth move I would
just put Icebeam, you can say sup to Flygon, and well its
good damage to Breloom and Claydol if T-tar is ever your
last poke or you lack a counter(which you shouldn't), so meh..
