Arcanine is a great support but your moveset does not offer any offensive presence on the field.
Now this is my idea to change a bit that Arcanine: change Moxie for Intimidate on Salamence, in this way you have 2 Intimidate users in your team, and you can get rid of W-o-W on Arcanine, which is a slow W-o-W user (compared to Gengar or Pranksters). Then an Impish nature instead of a Bold one, because we are going to use Wild Charge (a good answer to Mega Charizard Y if your Mega Salamence is not on the field, hitting Talonflame too) instead of W-o-W and Overheat (despite the -SpA nature, it's going to hit hard anyway) instead of Morning Sun to get some OHKO with a Fire type move.
0 Atk Arcanine Wild Charge vs. 252 HP / 4 Def Mega Charizard Y: 90-108 (48.6 - 58.3%) -- 95.7% chance to 2HKO
0- SpA Arcanine Overheat vs. 4 HP / 0 SpD Bisharp: 176-210 (124.8 - 148.9%) -- guaranteed OHKO
0- SpA Arcanine Overheat vs. 252 HP / 36 SpD Mega Mawile: 134-158 (85.3 - 100.6%) -- 6.3% chance to OHKO
0 Atk Arcanine Wild Charge vs. 4 HP / 0 Def Talonflame: 98-116 (63.6 - 75.3%) -- guaranteed 2HKO (that it's a OHKO after a Brave Bird damage)
So we can get a lot of damage without even investing EVs
You should also see this:
0 Atk Arcanine Bulldoze vs. 0 HP / 0 Def Heatran: 72-88 (43.3 - 53%) -- 13.7% chance to 2HKO
If you can't even get a 2HKO with a ground move on Heatran, there's no point in having Bulldoze.. maybe Extreme Speed to get some revenge kills? Or even Helping Hand!
@Last edit: Your team does not support an Earthquake, but you can run Rock Slide AND of course Protect on M-Mence, instead of EQ and FireBlast. And 252Atk/252Speed if it's SashBreloom - no point in giving 252Spd.
