Hey there, it's nice to see Moltres used, however you have some problem against Tyranitar, capable of stopping Moltres, your thundurus-t while he has grass knot he doesn't have focus blast, Garchomp could be killed by ice Beam also he can't ohko tyranitar back, furthermore Tyranitar brings Sandstorm, causing other problems to tentacruel.
So, have you considered Scarfterrakion over garchomp? He can come in on most Tyranitar attacks, scare him of with Close Combat, and he's also capable of helping you against sun teams, especially against Volcarona.
Hope it helped, good luck
