ohh, and i dont have items yet, just some low stuff, and Leftovers, some berries...etc

had no time to think about it...
but thinking about changin Chansey to...dont know :S maby a defensive Suicune?

Your movesets look all fine and dandy, although the most important thing with Battle Subway teams is that it's vital that you not only breed for natures, but also EV Train your Pokemon or else you won't make it into the depths of the line. What EVs have you got for them at the moment?

The way I see it, you have two main options in replacing Chansey: Suicune or Ferrothorn.

Suicune
Suicune gets great coverage alongside Volcarona, as well as with Garchomp.

Suicune @ Chesto Berry
Pressure | Bold
252 HP / 252 Def / 4 SpD
~Calm Mind
~Rest
~Scald
~Substitute
Suicune is a beast with this moveset. The EVs and nature allow for the highest amount of bulk. It can use the combination of Substitute and Rest to set up sufficiently with Calm Mind, and then sweep with Scald which has the added bonus of possibly burning the opponent.

Ferrothorn
Ferro covers Garchomp's Ice weakness as well as Volcarona's Rock and Water weakness very well.

Ferrothorn @ LEftovers
Iron Barbs | Sassy Nature
252 HP / 160 SpD / 96 Def
~Leech Seed
~Curse
~Power Whip
~Toxic / Protect
Ferro can provide Toxic support with this set while healing with Leech Seed. Curse makes it immensely bulky and Power Whip is its STAB move of choice for dealing with Water-types which would otherwise run rampant over your team. Not 100% on the EVs though.

well, thx for info, and i know about the EV training, i just need the items to train my Pokémon faster
shiny Gible is lvl1, jolly, will train to 4HP/252Atk/252Spe
IV's are fine i think, Atk and Spe 31, the rest are ~20+

shiny Volcarona is still lvl70 (stationary) UT, EVs will be 252HP/252SpA/4Spe
IV's are fine too, 29HP, 31SpA, 31Spe

dont have time and parents to go for perfect shinies atm

and i think i will try Ferro, cuz i dont have a bold Suicune, and can easily hatch a decent Ferroseed...so :D
btw the EVs sound ok, wht about 252HP/88Def/168Spd ? :)

and whats your opinion about switching Garchomp to Scrafty?
Jolly, Moxie, IVs are 31Atk/31Spe/20+ rest
4HP/252Atk/252Spe
