Makes no difference anyway.
Sawyer literally countered all of Ash's team, right down to the moveset. He called out Slaking in response to Hawlucha (which worked), Clawitzer in response to Talonflame (which worked), Aegislash in response to Pikachu (which very nearly worked->set up easy revenge kill), Salamence in response to Noivern (which led to a draw), and of course Sceptile saved for Greninja.
Unless Sawyer is allowed indefinite time between matches to change his Pokemon's movesets or switch Pokemon entirely, those strategies are what he retains. And they won't be as effective against Tyson.
So correct me but when Slaking is sent out wouldn't the logical decision be to send out a fighting type if you have 1? Slaking can be used to lure out a fighting type, scout their moves with its high bulk + recovery and then use Counter when said fighting uses its strongest move again (x4 Hariyama's Focus Punch = dead Hariyama). The primary reason that Clawitzer won so smoothly was because it could effectively halt Talonflame's momentum with Ice Beam and really that can be used on literally any speedy Pokémon that relies on high momentum for greater impact with their attacks. Also Clawitzer previously beat Novern + Luciha and has reliable recovery (and can even hit Grass types Tyson would likely send out against it with SE Ice Beams). Literally any Pokémon would have trouble with King's Shield (and no Steel resists Psychic so Metagross isn't manually removing the Shield with Psychic) and besides Kalos Pikachu was the most consistent version of Pikachu (16-4-0 record going into the Sawyer battle) so even if he wasn't in Peak mode he was still very powerful in his own right. Yeah "Protect"... wow what a major counter (definitely can't be used to at least scout an enemy attack mirite mate). Slurpuff can use his nose to land pinpoint surprise attacks when there's smoke from move collisions so that's a pretty neat general skill. Conserving one's Ace for last is a basic tactic (Tyson does it too and unfortuneately for him MS does have the net move advantage against Meowth).
There was nothing that Sawyer did which was overtly specific to Ash's team (barring maybe cutting trees down since Pikachu liked forests but that was improvisation and not a planned strategy) and not applicable in a more general sense. In addition Sawyer has been compared to Ash in that he's also very good at improvising (obviously not to the same degree but this should be noted). Also Tyson isn't exactly the kind of guy that would try very hard to give himself the optimal matchups (on a side note what even would be Tyson's ideal match play out). Sawyer's team in fact does seem to stack up nicely against Tyson's team and the only information Sawyer would need to know this would be what Pokémon Tyson is using which he could easily get if this were the next round of a league conference. As far as I can tell the most reasonable correspondence would be:
Slurpuff <-> Shiftry
Salamence <-> Donphan
Slaking <-> Hariyama
Clawitzer <-> Sceptile
Aegeslash <-> Metagross
M-Sceptile <-> Meowth
Which gives the following play out:
Slurpuff vs Shiftry -> Slurpuff
Slurpuff vs Donphan -> Donphan
Salamence vs Donphan -> Draw
Slaking vs Hariyama -> Slaking
Slaking vs Sceptile -> Sceptile
Clawitzer vs Sceptile -> Draw/Sceptile (heavily wounded and fatigued)
(If Sceptile wins: Aegeslash vs Sceptile -> Aegeslash with minimal damage)
Aegeslash vs Metagross -> Metagross
M-Sceptile vs Metagross -> M-Sceptile
M-Sceptile vs Meowth -> M-Sceptie
At best (for Tyson) there should be a lower moderate health Metagross (30%) + Meowth by the time Sceptile comes out and it should be M-Sceptile's game from there (though I will admit that this should be enough to edge out Base Sceptile). The playout I gave certainly doesn't represent Sawyer's idealized playout (e.g. Aegeslash vs Hariyama lol) and again I have to ask what is Tyson's idealized playout that would sc*** Sawyer so badly if he didn't have prep time?
You continue to stubbornly concoct more assumptions, interpretations, and denials to spin things to make sure Sawyer still draws/leads. I'm not going to argue further against a hopeless case.
Dude you officially lost all credibility here the moment you equated "don't remember Tyson too well" = don't remember Tyson. Please don't waste anyone's time any further with your conspiracy nonesense.
