Golem, Electabuzz, Ormastar, Snorlax and Aerodactyl (recently claimed) arrive. Let's rock.

Snorlax lays on Vulpix. Evolution advantage triumphs.
Golem crushes Arcanine. Splat. Rock/Ground advantage.
Electabuzz enjoys fried charizard, again. Electric beats flying.
Ormastar roflstomps Magmar with Hydro Pumpage.
Aerodactyl plays some awesome rock-n-roll to roll all over Rapidash.

Overall, I'd say that's a complete victory, hard mode win.
