626 Bouffalant

Mud Shot sports very fast energy generation and poor damage output, while Zen Headbutt is just bad period. 

Stomp costs the least amount of energy, benefits from STAB, and can be used frequently, though it can't be Super Effective. Earthquake and Megahorn are both powerful and efficient moves, each with different coverage depending on what the player needs. Skull Bash provides STAB neutral coverage, and a guaranteed buff to Bouffalant's DEF stage, but also costs the most amount of energy to use. 

As a Normal-type, Bouffalant can't benefit from both STAB and a Super Effective multiplier at the same time, which limits its damage output. While Stomp is recommended to bait shields, it's a direct downgrade of Body Slam, which causes it some close matchups. The limitation of choosing between Earthquake or Megahorn is a significant problem, meaning Bouffalant has to chose which Pokemon it wants to cover at the cost of losses against others. If Bouffalant decides to not pick Stomp and go for both big hitters, it picks up easy fights in exchange for bait-dependent matchups, but is also too slow for most 2-shield fights against meta Pokemon. Overall Bouffalant has potential, but its inefficient moveset largely holds it back. 

Bouffalant's Normal-typing is useful against Ghost-types, though it's cumbersome moveset may cause it to struggle against the overall meta. Just like in Great League, Bouffalant has to choose its moveset coverage and pick certain Pokemon to cover at the expense of others. While Bouffalant can win against other Normal-types in this meta, it may not necessarily be the best candidate for that role. 

With a max CP of 2797, Bouffalant would appreciate more stats for Master League.
