Toxic/Triple poison

[Composer of Requiems]

I'm working on my deck, currently, I have the following concept:

Beedrill (With triple poison)
Beedrill (With poison spray)
Tentacruel (With Toxic)
Blissey (With happy healing)

The concept was to do damage, especially poisoning, and switch out when they are damaged. Blissey's happy healing can help to heal bench. The three pokemon listed above (except blissey) have zero retreat cost, so i can cycle them. My deck also has rare candy (i can't seem to find anyone selling pokemon breeder), Pokeball, Pokenav, Jirachi, etc. to dig out the pokemon and evolve them into the final forms.
I'm planning to add in a Crobat from the hidden legends series. It also has Triple poison and zero retreat cost. What do you think of this concept?
Also, do you know any other pokemon (excluding Nidoking) with Toxic or Triple poison?

Instead of Speedrill, try going with HL Crobat. Same Triple Poison, no flip.

Plus once you've poisoned the opponent, You can use his other attack to make your opponent discard cards. nothing is meaner in my opinion. :D Crobat is so cool.

Humm... For Special Condition Decks I would say Mirage Stadium is good =p
But Switch still bypass it -.-;;
