I've brought this up many times before, Pinsir and Talonflame need to drop to A rank. Charizard Y's drop was the nail in the coffin. Like Charizard Y, both require a bit much support and are not as strong as the A+ mons in terms of what they bring to the table. They're pretty good, but not great, and the list should reflect that.
and
->
A rank
I would say Taloneflame stays at A+ simply because priority bravebird is so damn good, and the fact that it can run many viable sets, but I would agree with M-Pinsir. It's powerful when it gets an SD, but it NEEDS an SD to sweep, and it's just so hard to get one up.
You seem to be severely underestimating Greninja. Hes easier to bring in than you think, especially when U-Turn and Volt Switch are almost anywhere. And honestly, STAB on everything, as well as a good special attack stat and great speed tier, allows him to revenge kill basically every non scarfed Poke in the tier. Sure, Deo-S can do that as well, but Deo-S doesnt get STAB on everything, nor is he able to use U-Turn, which is another big boon for Greninja. Thanks to the switches he forces, he provides momentum for the team, which is something Deo-S simply cant do. Greninja is a hit and run attacker, and definitely one of the best ones out there. Proof of this is the fact that most teams end up being weak to him if the lack Chansey, and the best they can do is soft check him.
>Getting lucky on Double Switches
I dont think you understand what double switches are meant to do.
Right, and as I said, on a U-Turn/Volt-Switch team, Greninja can work. But not every team runs that, or even has room to run that. Maybe it's because i typically run stall that I never seen to have trouble with it, but I've never really had trouble with Greninja. Normally I just switch to my special wall (either Chansey or my Avest Kyube) and I'm good to go. It really does struggle against stall, which is becoming an increasing more played play style.
As an aside, it really can't revenge kill as much as you think it can
Aegislash
Can do a chunk to with Dark Pulse, but get's KOd by Sacred Sword, so can only revenge kill if Aegi is at less than 75% health
Charizard (Mega-X)
Normally would be able to, but if it's revenging a Char X, then Char X is probably at +1 anyway, so it's useless against that
Deoxys-D
Wins but takes a lot from Superpower and life orb damage
Deoxys-S
DeoS is faster and KOs it with Thunderbolt
Landorus
wins
Thundurus
Wins
A+
Azumarill
can't touch except with Hp grass, is destroyed by Avest Azu
Bisharp
Wins, but takes over half it's health from Sucker Punch
Clefable
If it's revenging, Clef probably has a +1 in spdef, so it loses. Even then, Clef can most of the tim, set up on it unless greninja gets really high damage rolls each time
Excadrill
Wins except for Scarf or Sand Rush in Sand
Garchomp
Can't revenge Scarf Chomp, otherwise wins
Gyarados (Mega)
Cant' touch without HP grass, can't revenge if at +1 (which it probably is if you're revenging it)
Keldeo
Wins
Mawile (Mega)
Loses if M-Mawile is at more than 80% health, takes a good chunk from Sucker Punch, otherwise wins
Pinsir (Mega)
+2 Quick Attack has a 62.5% chance to OHKO so most likely loses. either way, it'll die next turn from life orb damage
Has a 18.8% chance to KO with Bug Bite (assuming Bulky Sweeper), Greninja can only KO if M-Scizor is at less than 68% health. If M-Scizor is at +2, Greninja is 2HKOd by Bullet Punch, and always OHKOd by Bug Bite. So most of the time, it loses
Talonflame
dat priority mane
Tyranitar
Hydropump does 65.5 - 77.9%, and Stone Edge OHKOs 31.3% of the time. Greninja gets OHKOd by Banded Ttar, flat at loses to Assault Vest
Tyranitar (Mega)
If at +1, M-Tranitar outspeeds and OHKOS, which is likely if you're revenging it. Either way, Greninja can't KO unless M-Ttar is at less than 80% health, and will always get KOd by Stone Edge + life orb damage
Venusaur (Mega)
Wins but takes a lot of damage in the process
It can only reliably revenge kill 6 of the top 21 pokemon in OU
Whereas Deoxy-S
Aegislash
Loses
Charizard (Mega-X)
Has a 50% to OHKO, so most likely wins unless Char X is at full health
Deoxys-D
Wins I guess
Landorus
Wins
Thundurus
Wins
Azumarill
Does a huge Chunk with Psycho boost however can only KO if Azu is at less than 92% health, takes only about 40% from aqua jet. In most situations, wins, however not always. Loses to Belly jet
Bisharp
loses
Clefable
loses
Excadrill
Wins unless sandrush
Garchomp
Wins
Greninja
Wins
Gyarados (Mega)

Azumarill
70 - 82.6% so can win if not at full health, otherwise loses
Bisharp
Never OHOd by Sucker Punch, KOs with Flare Flitz, so wins
Clefable
Wins unless Thunderbolt
Excadrill
Wins unless Scarf or Sand Rush
Garchomp
Does large Chunk with Brave-Bird, but most likely loses

Wins
Pinsir (Mega)
Wins
Wins
Tyranitar
Loses
Tyranitar (Mega)
Loses
Venusaur (Mega)
Wins
Talonflame can reliably beat 10 of the top 21 pokemon, and reliably wins against most of them if they're not at full heath.
keep in mind this is only in terms of revenge killing, which is what's being argued as Greninjas strong suit. To me it seems to just inferior to both talonflame and Deoxy-S in terms of a revenge killer. The only perk it has other either of them is not being weak to stealth rock and U-Turn, but U-Turn forces it to be even less bulky than it already is, which can really hurt it.
Read my previous post I made just before you for Zard Y.
What sweeper isn't checked by Thundurus-I, again?
Scarf Excadrill is obvious (no Sand support and no Air Balloon message means it's Scarfed) and a free switch in for a ton of things. Air Balloon Aegislash is a massive middle finger to you, for example.
Sand Rush Excadrill only checks with Sand up.
Rotom-W takes 57% minimum from a boosted Return and is not hard to wear down.
Max HP T-Tar is always OHKO'd by a boosted Earthquake. ScarfTar can check you.
Rain Sweepers do not resist your STAB and need Rain up to check.
Talonflame is a fair point.
+2 Return does up to 60% to Zapdos, meaning if has to be healthy to check.
+2 Earthquake does up to 80% to Rhyperior. See Zapdos.
Alright, this has been bothering me for the longest time, but why is everyone automatically putting a +2 in their calcs? The only reason I did it is because it was the situation of revenge killing, which in that case, if M-Pinsir had KOd something, it probably has a +2. But otherwise, a +2 is nowhere near guaranteed, and that's the exact reason why I feel it should drop to A, because it NEEDS the +2 to do anything.
Also your calc on the Rotom-W is ridiculous because nobody in their right mind would let a M-Pinsir SD without switching to their Rotom-W the turn it SDs. So the real situation is that the M-Pinsir does about 50-60% to the Rotom-W, Rotom-W burns it, pain splits off some damage, and then KOs it with volt-switch.
