So, while planning the type advantages I felt like I was letting the original typings control me too much so I made everything be x1 in an image file, went around doing what I felt would be good and here is the result:
I'm pretty happy with it so it'll probably stay that way ;D
-Almost all pokemon have 480 stat total (the sum of base HP, Attack, Defense, Sp.Attack, Sp.Defense and speed that calculates the pokemon's stat) with 2 exceptions: Shedinja has 401 and Slaking (being now the ONLY pokemon with the Truant ability) 600 (480+120 to the HP stat).
-Starters are Eevee, Pikachu and Clefairy
-Pikachu evolves with the Thunder Stone, Clefairy with the Moon Stone and Eevee evolves into Vaporeon with the Water Stone, Jolteon with the Thunder Stone, Flareon with the Fire Stone, Espeon with the Sun Stone, Umbreon with the Moon Stone, Leafeon with the Leaf Stone and Glaceon with the Shiny Stone.
-Normal starters (like Snivy, Charmander, Piplup etc.) all evolve with leaf, fire and water stones instead of levels.
-Various moves have been modified and TM49 is now Tri-Attack instead of Echoed Voice.
-Politoed and Poliwrath are now 4th evolution since Tympole is now a prevolution of Poliwag. Tympole evolves into Palpitoad if taught sandstorm via TM and leveling up.
-Zubat evolves into Woobat after using a Dawn Stone (Zubats are now found in the world instead of Woobats)
-Kirlia evolves at level 30 into Gallade if male and into Gardevoir if female. (Kirlia's 2nd ability trace becomes pure power for Gallade and Serene Grace for Gardevoir)
-Legendary Pokemon can now breed and are legendary because they've got extra given EVs (All pokemon have 3 given EVs and legendaries have 6) which makes them easier to make powerful. (easier to get them there but they're not better, a Rattata is just as powerful as anything now ;D Even though it's strong stat is speed.. Oh well..)
-Trade evolution pokemon usually evolve either via level, level with held item and in the specific cases of Karrablast and Shelmet: Karrablast evolves when holding a protector and Shelmet when holding a shed shell.
And those are some of the changes; I'll make a full list of changes to Pokemon and moves in a PDF or something soon, no story changes have been made yet and I'm currently testing but if you want to try it out:
