I like the idea of combining Gemini Light Beat and Chaos Stun. I would focus more on the anti-meta aspect. Drop some monsters for more removal. I would probably drop the psychics as they seem to be there only for slow synching and Chaos/Allure food. There's better cards you could run. Run 3 pod in all kinds if anti-meta, and yeah drop upstart, run 0 or 3 upstart, that's just the way it works (I would run 0). Mst is good and underrated. So maybe:
-1 krebons
-1 commander
-1 upstart
-1 mind control (I only like this in decks with 5+ tuners)
-1 featherizer
+2 mst
+1 pot of duality
+1 bth
+1 awesome light monster
also consider switching your monster lineup a tad to incorporate TKR in the main. He's not a spellcaster but w/e, he's awesome and he's a light for Chaos. Also consider Solemn Judgement. Some prefer not to use it but it still pwns...if you want to run it drop 1 seven tools
