It is a shame you lost that game
technically you could use mindgates, and add buff cards and mindgates to the opposing deck. There are 14 permanant spots- 1 taken up with pillars. so 13X chaos power with +5 attack.
Hand: 2 skyblitz + 4 SN + 2 CP
(499+65+10) *2(dive)*2 skyblitz *2 skyblitz(4SN) = 4592 damage.
Or you can add SN and skyblitz to the opposing decks. get a 499 attack wyrm. 12 mindgates to receive 12 SN.
Hand: 4 Skyblitz +4CP
(499+20) * 2(dive) *2 skyblitz *2 skyblitz(4 SN) *2 skyblitz(4SN) *2 skyblitz (4SN) = 16608 damage
I think you can go higher if you used basalisk blood before and rage elixirs instead of chaos powers. and in the second scenario have the 13th permanent be an hourglass to draw you another.
