The middle spots are the most important. Your starter is an obvious choice for the free space, but Butterfree may be useful as well, thanks to Confusion's effectiveness against Zubat. It might also be worth capturing a Geodude or Sandshrew simply to fill the spot on the high ground.

Remember, it is possible to change a Pokémon's moves mid-battle. Switch moves to counter different waves. Alternatively, move your team back and forth as waves come from the left or right sides.
