Blaziken

Great League: 3 / 5

Blaziken first gained popularity during the Silph Arena Kingdom Cup in April 2019, where its ability to "Counter" the ubiquitous Lucario and Bastiodon earned it a position on many rosters despite its slow moveset. With the addition of two useful moves added to its moveset on Torchic Community Day, Blaziken notably moves up the ranks thanks to a faster moveset. Blaze Kick is the main improvement, allowing Blaziken a low cost charge move option energy-wise, which removes Blaziken's reputation as a late game nuker and lets it brawl in early and mid-game. Previous losses that are now wins (under 1-shield scenarios) include Froslass, and almost all Grass-types. Blaziken's low durability is still its main drawback, as a high ATK stat distribution lowers its overall bulk and causes it have close results with Meganium instead of clean wins. 

Ultra League: 3 / 5

A higher CP cap benefits Blaziken's high Attack stat and results in more wins, though a lack of bulk still holds it back. Obvious wins against Steel are to be expected, though narrow victories against Grass-types are somewhat disappointing considering typing advantages, and Giratina can't be touched by it whatsoever. Overall a very interesting candidate, just be prepared to shield it well to preserve its limited endurance. 

Master League: 2.5 / 5 

With a max CP of 2848 Blaziken doesn't really have adequate stats to compete well in Master League. Wins and losses are to be expected where type advantages apply, though Blaziken can return interesting results depending on shielding situations against Dialga. Just like in the other leagues, Blaziken almost demands shields to perform well.
