Yeah you'd probably be better off with Dragon Claw and Earthquake and then running Magnezone to take out Skarmory and Bronzong. Earthquake also benefits from the Atk boost from Moxie.
Although, I'm still not really sure what Substitute helps you do, especially considering the fact that you can't use Intimidate to make it so weaker physical attackers can't break your Sub. Ferrothorn will get OHKO'd by LO Fire Blast and you can always start off by using Dragon Claw mid-game to hit whatever comes in as there aren't many Pokemon that can both outspeed Salamence and resist Dragon Claw.
My Trick Room team peaked at 6th out of 2668
in the Wi-Fi ladder on Pokemon Online.
