1 Skill Drain >>> Fiendish Chain - Skill drain stops all effects on field, fiendish chain stops only 1 and besides you have to side Shadow-Imprisoning Mirror. 3 Photon Thrasher is pro (I rarely even draw it, its such a good first turn play if you do not have stratos). And you want to special a lot in this deck so 3 PoD kinda screws you.
I prefer fiendish chain becuase of high attack beaters that I can't run over when I don't have the right cards. SKill drain stops their effect, but fiendish chain stops their effect and stops them from attacking.
Maxing a card does not make you pro its just a prefrence of a duelist imo.
ugghhh i dont like the thrasher usually pro bubble beat plays with 7 monsters. thrasher is such a dead draw in my opinion. i suggest to take out the thrashers and main deck the msts. that would be a lot better. after that side 2 soul takers for those annoying chaos dragons.
