I managed to beat it without much problems using Astall and setting my units to the same element as my friend's. Funny thing is that I brought the wrong element seals and didn't need to use them at all.

I would advise taking Elemental Stones or Seals to boost your stats (most importantly, Def) along with Def Elixirs, Cures, and Revives. I took along 5 Seals, 10 Cures, 7 High Cures, 2 Crescent Dews, and 2 Revive Lights. Astall had Growth Device and Beiorg's Armor to tank through Duel-SGX's attacks easier.

If you don't have Astall, there are other units you can use such as Kaiser Glowy, Eclise, Lin, etc.
