Two kids no brane
I want to make a case for dropping Lillipup to mid tier. Yeah he's decent for being gotten so early, but his offensive capabilities simply do not keep up. He has a surprisingly shallow movepool as far as in-game moves go (until you have access to the fangs with Heart Scales), so his utility is pretty much limited to Intimidate (if he has it) and sponging a bit with his respectable defenses. By the time you reach the later gyms he is being beaten 1 on 1, and takes too long to set up to be much threat. I think he definitely deserves to be in the higher part of the middle tier, but he's not useful enough throughout to be at the top.
