You level it up to lvl 36.
To get charizard on Pokemon leaf green you have to choose charmander as your starter. You have to level it up until it evolves into charmeleon at lvl 16 and then level it up again to lvl 36 and itwill evolve into a charizard :)
Clefairy does not evolve through levelling up, you must obtain a moonstone and use it on it. (There are three moonstones in the game)
action replay quick level code and you can leave it in the day care but beware it learns all the moves it learns as it levels up so get your Pokemon uo to about lvl 50 then put it in the day care+add a year onto your calendar and the Pokemon in the daycare will be lvl 100 hope this works!
Now answering this question is fun because my lead Pokemon is a Persian Lvl 100 Shiny Female (completely Legit found it as a lvl14 meowth in leafgreen) You need to catch a Meowth From a previous game or Soul Silver and Lvl it up to lvl 28 Hope This Helps- Signed The Girl Pokemon Master

You level a Pokemon up.
you train them!!!
Level them up.
That depends on the type of Pokemon that is leveling up.
Train the birds up but get a thunderstone to let pikachu go into raichu and your team is ready to go.
Usualy speed desides unles someone uses quick atack then that Pokemon atacks first
