Help with last two members? or suggestions

I am doing a random run through of the game I currently have Delta Liligant
Delta Golurk Delta Larvesta Delta Gardevoir

So let’s see, you’ve got Fighting/Steel, Ice/Electric, Dark/Poison and either Water/Fire or Fairy/Flying.

That’s not a wide variety. I’d throw in probably a ground type, Psychic type, bug … hell even Dragon.

Though where are you in the game?
