Blaziken

Blaziken is one of the best non-shadow/mega Fire Types in the game currently. With Blast Burn, it tops the DPS charts, though its TDO isn't the best. And even with Blaze Kick, it still has a great offensive presence that can't be ignored. Some players even take advantage of Blaziken's super cheap second move cost to run these two moves together and throw out a last second Blaze Kick if they know that Blast Burn won't be charged in time.

As a Fighting Type, Blaziken is usable, but not optimal. It falls behind the big-names of the type, and can't touch shadows. It's fine as a budget Fighting Type, but it does better work as a Fire Type.

We do recommend that everyone raises at least one Blaziken at some point, as Mega Blaziken is set to have the highest general DPS among all Fire Types.

Best PvE Offensive Moveset

• Pair Blast Burn* with Fire Spin for unparelled Fire-type DPS.

• Use Blast Burn* + Counter for higher DPS against Ice or/and Steel-types.

• Pair Counter with Focus Blast for a formidable Fighting-type Pokemon.

• Blaze Kick has been nerfed. It's still better than Overheat.

• Overheat is inferior to both new moves and not worth using.

• Brave Bird is underwhelming in every aspect.

• No one actually has Stone Edge. It's also not useful in PvE.

Best PvE Defensive Moveset

• Fire Spin is slightly superior to Counter on defense, hitting more of Blaziken’s counters for neutral damage. However, Fire Spin also has the issue of sharing a type with Blaziken's best defensive Charged Move options, leaving it easily walled out when against anything resistant to Fire.

• Blaze Kick hits fast and furious, but it's best paired with Counter to keep different typings.
• Blast Burn has the highest potential damage output of Blaziken's Charged Moves, but it's also easy to dodge, and is best paired with Counter for the reasons outlined above.
• Brave Bird hits hard, but it lacks relevant counter-coverage and takes a long time to drop. Chances are that Blaziken will drop long before it's used.
• Stone Edge has a useful typing and is hard to dodge, but Blaziken will probably drop before it's used.
• Overheat and Focus Blast hit extremely hard, but they're also easy to dodge and yet more moves that Blaziken will probably only be able to launch once, if at all.

Counter outperforms Fire Spin and also gives Blaziken some coverage in this moveset. 

What has been anticipated for more than a year has finally arrived, in the form of 2 unique moves. Blast Burn is capable of massive damage for relatively low energy, while Blaze Kick is a mirror copy of the elemental punches and gives Blaziken some speed by allowing more smooth shield baiting. While this moveset doesn't necessarily help Blaziken cover its weaknesses, it does let Blaziken dominate its wins much more cleanly. Brave Bird can be elected for extra coverage, though STAB Blast Burn is more efficient even when resisted. 

A more flexible but very limited moveset that gives Blaziken some coverage, though depending on the matchups this might not matter as much. If you have the legacy Stone Edge, definitely keep it and unlock Blaze Kick to have this option, but this moveset isn't as significantly different as the previous one. It should be noted that without Blast Burn, Blaziken can get different results depending on matchups.
