In Preparation for XandY's froggy starter, I'm putting together an amphibian team to trade in later. i'm letting natures, IVs, and genders be random but I will be EV training. I'm building most of my team for survivability over damage, but I'm not sure how to divide up the EVs. I was just going to try to put all the EVs into HP, Def and SpDef.

Here's my team:

Politoad - Drizzle
*leftovers
scald
icebeam
encore/protect
[toxic?]

Poliwrath -water absorb
*leftovers
rest
sleeptalk
circle throw
scald

Swampert - torrent
*leftovers
earthquake
waterfall
icepunch
roar

Quagsire -unnerve
*leftovers
earthquake
recover
stockpile
scald

Toxicroak - dry skin
*black sludge
swords dance
substitute
drain punch
suckerpunch
[ice punch? stone edge?]

Seismitoad - swift swim
*leftovers
earth power

sludgewave
[rain dance?]


alternate:

Ludicolo
- rain dish
*leftovers
giga drain
