Overgrowth reborn

[UDC]

The following deck is loosely based upon the overgrowth deck from the 90's, overgrowth from base set.

Legend:
SW: secret wonders
RR: rising rivals
GE: Great Encounters
U: HS unleashed
SF: Stormfront
DP: Diamond and Pearl
LA: Legends awakened
MT: Mysterious Treasures
Right, I was bored and picked up overgrowth at a toy store and was inspired to re-create it. So, without further ado-

Spoiler:

1x Venusaur (SW)
1x Ivysaur (SW)
1x Bulbasaur (SW)
1x Beedrill (RR)
2x Kakuna (RR/GE
2x Weedle (RR/U)
2x Gyarados (SF)
1x Magikarp (MT)
3x Magikarp (SF)
1x Blastoise (U)
1x Wartortle (U)
1x Squirtle (U)
1x Sceptile (SF)
1x Grovyle (SF)
1x Treecko (SF)
1x Manaphy (DP)
1x Regice (MT)
1x Miltank (SW)

4x Pokéball
2x TM TS-1
1x Rare Candy
1x Professor Elm's Training Method
1x Holon Mentor

12x Water Energy
12x Grass energy
2x Scramble Energy
1x Rescue energy
1x double rainbow energy

The main objective is to discard 3 magikarps, and evolve the 4th into a Gyarados, which would then proceed to use tail revenge for completely free. Regice is used to discard Magikarp, and Beedrill to gather other grass types. Miltank is responsible for healing most of the pokemon with the exception of Sceptile and Venusaur. Blastoise can move energy to the active pokemon as often as it likes, and Sceptile can just move energy around. And TM TS-1 is self-explanatory :)

So, what do you think?

Before I talk about this deck, I would like to know if you're just building this for fun or for competitive play. I can suggest a revision if you intend to run the deck for fun or if you want to run a deck in the current format legally. Because either way I have some suggestions:

-Stronger evolutionary lines; i.e. at least 2 basic, 2 stage 1, 2 stage 2, as far as the line goes.

-Less evolutionary lines; mainly take out beedrill and sceptile, venosaur is okay to stay if he sits on the bench, otherwise pitch him. Ideally with this deck setup, you should set up Gyarados quickly and start chaining off tail revenges while bulking up Blastoise on the bench. You should normally only run about 1 or 2 stage 2 lines in a deck; either 2 different lines or 1 filled out as much as needed.

-More supporters: you have 2 supporters. That does not bode well for you with as many lines as you're trying to run now, and regardless you should have a good 20-30 trainers and supporters in your deck.

-More trainers: realistically you should be running at least 2 rare candies for every stage 2 line. The max is 4 candies, and you shouldn't be running too many stage 2 lines because they're slow to set up, and realistically impossible with low numbers like you're using.

Less energy: You have too much energy. I'd reccomend cutting the grass energies and keeping the rest.

Right. I'll take these considerations into mind and try and revise my deck. Thanks! Personally though I think I should keep Beedrill to get Venusaur set up though. Unfortunately I don't have anymore rare candies...
Also, this is a non-competitive deck. Most of the cards are outdated.
