keep blaziken,gardevoir and groudon.
ditch breloom for an electric type like manetric. you already have a fighting type which is blaziken.
if you can, get a milotic or swampert instead of wailord. they have better stats and ability.
swellow should be replaced later in the game or if you can trade, with salamence. although its 4x week to ice, thats why you have blaziken and manectric.
