Good Pokemon Team?

[Blibbering Humdinger]

Hi! Is this a good pokemon team for Heart Gold? I transported pokemon from other games.

Cyndaquil(to be let evolve) FIRE male

Treeko(to be let evolve) GRASS male

Piplup(to be let evolve) WATER male

Ralts(to be gardevoir) female

Skitty(to be Delcatty when it evolves) female

Swablu (to be let evolve) female

Thanks! They are involved right now, but they will evolve!
I love skitty

PS I am a girl of course, to be choosing those pokemon.

If you're just making a team to beat the game, you can use just about anyone as long as they reach the right level to be powerful enough. However, you might want to consider swapping out Treecko for Turtwig or Piplup for Mudkip to fight electric types (I would take Turtwig personally). Also, ditch Skitty. She's cute but not too useful. Gardevoir is an excellent psychic type and Altaria is pretty sturdy (she can also learn sing!) and Typhlosion has solid speed and special attack. Hope this helps! Good luck.
