I thought that at least the BoL + Sky Blitz + Fractal combo already exists?
Well, not having much time today I might try a deck tomorrow (if I remember =P)
I don't know just how common BoL + Sky Blitz + Fractal is but I know I tried it once. I ended up finding that having my hand get clogged up meant it was inconsistent and slow. Maybe I just got the balance of fractals and blitzs wrong but I ended up moving to a BoL + Fractal deck reinforced with recluse which lead me to a Fractal + Recluse + Dimension shield HB farmer with something like an 80% win rate upped although I only did about 20 games. Yeah, I ramble.
Wait, is this for level 3 or 4+ because for level 3, 6 blitzed balls is 60 damage, maybe try dropping the fractals, taking damselflys and going down the air route with something like:
6 BoL
6 Damselfly
6 Blitz
15 Wind Tower
3 Eagle Eye
The Eagles + damselfies might give it consistency while still allowing fast wins.
Going down a general blitz route, I have vage memories of 2 versions:
6 Blitz
6Damselfly
6 Elite Wyrm
12 Wind Tower/3 Wind Dragon + 9 Wind Tower
6 Blitz
6 Wind Dragon
6 Damselfly
12 Wind Tower
Next time I'm on a pc I can test some or try to see if I've got a code and stats saved somewhere in my mess of saved notes, spreadsheets and screenshots.
