Someone recommended Nightmare on Butterfree. My issue with that is this is Butterfree with no CPoundeyes, meaning 75 accurate Sleep Powder. Nightmare was also the only way it would eventually stay relevant in later stages before completely falling off.Here are the first 3 leaders for Butterfree and Nidoqueen.
Butterfree at level 10 2HKO the pidgey and a range for a 3HKO on the pidgeotto, while taking 3 damage from tackle and 13 from gust while having 35HP on my butterfree. You also outspeed everything. You can win with a berry and getting the range on the pidgeotto. A more consistent strategy is to use harden to reduce damage of gust since the pidgey can barely do anything. Good matchup overall.Butterfree at level 16 is a 2HKO on the Metapod, 1HKO on the Kakuna and a 6 to 7HKO on the Scyther with confusion who will beat you with fury cutter. Scyther also outspeeds you. You can win if you sleep powder it to break the streak of fury cutter because it intially does piss for damage. Good Matchup overall.Butterfree at level 17 1HKO the Gastly, 2HKO on the Zubat and 5HKO on the Bayleaf with confusion. A bite from the Zubat does 4 damage and a crit razor leaf also does 4 damage. You also outspeed everything. Flawless matchup except for minor chance of confusion from the Zubat.Butterfree is decent with the combination of sleep powder, confusion and decent speed. He can muscle past things he honestly shouldn't because sleep is op. The lack of stab sucks though. I do foresee some gym leaders to come being very problematic for Butterfree.Butterfree at level 20 is a 5HKO on the Clefairy and 7HKO on the Miltank with confusion. You get 2HKO from rollout if you do not use hardens on the clefairy. This is unfortunately an RNG fest because of metronome. You also get outsped by the Miltank. Ok matchup at best because of sleep powder. Mine also was male and had big problems with attract.
Nidoqueen at level 20 2HKO the clefairy and 3HKO the Miltank with double kick. You are outsped by the miltank but if it uses rollout it starts at 2 damage and you outdps the increase. Good matchup overall.
Nidoqueen has a very long backtrack back to your home town to dump all your money to get a moon stone early. Some may not see this as worth it at all. I did not mind since she trivializes the Whitney fight but I understand the other point of view. Not much time to grow an opinion on her but no stab kinda sucks. Good coverage though.
Make sure you get Tauros in a Friend Ball for an instant nuclear option in Return. (A bit hard to do seeing a Tauros is hard to find, has a low catch rate, and Friend Ball isn't exactly efficient in terms as you get only one per day, requires Surf and Cut to obtain, and a wait time of a day to recieve. However, Tauros does nothing to Morty anyways as Pursuit is level 26 and uses his base 40 SpA. No Mud-Slap either.)
