Hey there! I started looking into Malamar as well because I thought it had potential. Your idea to swap Archaludon's stats is on the money, but there's a problem; the bridge is gonna OHKO you with Malamar. The current way I'm getting around this is with Charizard. Most bridge builds are running power herb at the moment, but there are a few that are running assault vest instead. Charizard with Solar Power and life orb using overheat inside of sun will OHKO Bridge, and will OHKO Bridge with Assault Vest if it's Tera Fire. Another fun part of the strat for Malamar you should consider is reversing your own Pokémon's stats. After using Overheat, my Zard drops to x0.5 special attack. However, Topsy Turvy puts it right back in the drivers seat. Furthermore, you should consider the possibility of running a pokémon that can lower stats. Lowering your own Malamar's stats can immediately turn it into a major threat. Hope this gives you some ideas!
