u should be able to play sopa on turn 2 with 1 water pend in your initial hand rather than on turn 3 if u fuel sopa only with the mark
i run water pends over nova because rather than the version with weapons/dials, sopa is always the first target against pc, so if u need to play 2 sopa u can do it easily
for drawing consistently things u need at least 5 copies of that card, sky blitz/holy flash doesn't change nothing; the only variation i can consider is add 1 or 2 sofree just for not automatically lose against dims
if u want blitz play balltal/damsetal (i even consider it but isn't reliable), sosac decks are rare and already screwed up by sopa
just played against my plat deck currently at
22/0, build to be an antimetagame deck with aoe + pc
i've won because i was able to play 2 sopa in a row at the beginning
