Attack: Lightning L-Drago 100 RF/R2F
Defense: Earth Pegasus II GB145 RS
Stamina: Earth Pegasus II 145 WD
Those are the best that you can make out of your parts. I advise of you to get a better CW for Defense and Stamina, as well as a better MW for those. For attack, you have pretty good parts. That combo is an out-dated combo, however.
Try getting Twisted Tempo, Ray Striker, Storm or Hyper Aquario, an MF-2, and Gravity Destroyer. That way you can make:
Defense: MF-H Twisted Aquario GB145 CS
Stamina: MF-F Twisted Aquario AD145 WD
If you want, you can get Vari Ares or Blitz Unicorno to improve your attack combo, but those can be expensive, because Blitz Unicorno comes in The Strongest Blader Set. Rather than the purchases mentioned above, you could opt for the Strongest Blader Set, as it Includes Twisted Tempo,and MF-2, and Blitz Unicorno. That way you would only have to buy Gravity Destroyer, Ray Striker and Storm Aquario. But, the first option might be better if you are on a tight budget.
