it’s not that it’s predictable, it’s just god damn stupid, you can predict it all you want, it’s still going to win
using power up punch over sword dance as your set up move is risky as ghost types are very likely to switch into you and without the boost, you won’t be dealing a dent as a regular flare blitz can’t get by his “counters”
for example, assuming you’re running jolly, a +0 flare blitz is a 4HKO on jellicent, a +1 flare blitz is a 3HKO, and a +2 flare blitz is a 2HKO
so now, why does it matter if it’s a 3HKO or a 2HKO, well, outside of the rare choice specs set (which isn’t very good), jellicent can only 2HKO, why is this a good thing? well… you outrun jellicent so unless you decided to use high jump kick instead of swords dance, you win this match-up
the only way to beat chandelure is with shadow claw
you have about a 40% chance to 2HKO azumarill if SR is up at 0, and a 30% chance to OHKO him if SR is up at +2 (i’d try to hit him on the switch and then switch out of there, as a choice band set OHKOs blaziken with aqua jet)
talonflame can only revenge kill
moltres ruins you if SR is not there, if it is, it’s 2HKO’d when you’re +2 and can’t do squat
dragonite is the reason you want SR up, he’s 2HKO’d after SR
everything else who tries to stop you gets wrecked
while you are allowed to do what you want to do, i’m just stating that there is a reason why everyone uses the latter set as it’s way harder to play around even though it’s “predictable”, you also have the option of using baton pass over protect but with all the priority and probably the build up of your team, it doesn’t seem like it would fit
also, while you think your set might be more flexible, it isn’t, by not using high jump kick, you are walled to oblivion by a bunch of things, even if you get the critical hit on shadow claw on something that resists fighting and fire (like azumarill), it’s BP is 105, a resisted high jump kick BP is 97.5, not a big difference, it’s still a 2HKO either way
the only thing shadow claw benefits you is that you can hit chandelure and have a 75% chance for a OHKO after SR on jellicent
to add, tyranitar is an excellent partner to blaziken as ttar crushes most of the problematic pokes for blaziken and sets up SR reliably so basically…you could win the game with those 2 pokes alone
