I know this has been posted a lot, but I chose some diferent pokemon. Could everyone give me suggestions on how my team is. This is the team I'm going to end up in the E4.
Also could you tell me what moves to end up with it. And I can trade from FireRed.

Your team seems fairly balanced, I rarely end up like that since I use my bias favs.

You could try giving Rapidash sunny day and solarbeam and the last move can be something to give neutral damage to another fire type like, return?

Pidgeot I have no idea since I only use it as support.

And the others I rarely use so I have no idea for those except Alakazam has many possibilities. You can give it focus blast for dark/steel types, that high powered grass move, shadow ball, just give them moves that you think you will need.

You don't mention which elite four so I don't even know what types you will face, good luck!
