i think i did remember posting an analysis of Flocessy Azurill vs. R6 Marill, what i got was that both are essentially similar in their roles that the only thing Azurill is notable in is the period where it exists before R6 which isn't very significant, considering you have Lillipup and Patrat to contend with. Marill's useless against Burgh (grass types everywhere) and Elesa anyway.
in essence, R6 Marill = Flocessy Azurill, so if you don't like Azurill you can just grab R6 Marill and still get what's basically the same thing, which gives you the breathing room to raise something else (zubat, riolu, lillipup and mareep all come to mind)
@raikaria: the only thing holding dunsparce back is stupid rarity (5% in rustling grass FTW) and its mediocrity after earlygame. it's kind of like jeigan in FE, useful early on then starts getting outclassed by everything midgame...
also uh cherubi is not available, i assume you mean petilil?
