I just got octane from the oracle and threw this deck together quickly:
5lg 5lg 5lg 6ts 6ts 6u7 6u7 6u7 6u7 6u7 6ve 6ve 6ve 6ve 6ve 6ve 6ve 6ve 6ve 7k0 7k1 7k1 7k1 7k1 7k1 7k1 7k2 7k2 7n2 7n2 7n2 7n2 7n2
obviously, it has some rares in it and the animate weapons at least will need to be upped, but it was very effective(only a last turn EE being played prevented mastery and I had 2 antimatter and a miracle left in my hand at the end). I did forget about him having the Fire Buckler which made me worried about decking out for a moment but by not animating one MG until I had another one in hand, I was still able to do enough damage with several turns to spare. Unupped Morning Stars would probably be better for this reason due to the much higher HP and only 1 less attack.
Also made up for the lack of mastery by winning 2 cards(ironically, one of them being the Fire Buckler
)
