252 +2 Atk Life Orb Blaziken (+Atk) Flare Blitz vs 252 HP/252 Def Slowbro (+Def) : 67.77% - 79.7% (2 hits to KO)
It cannot switch in safely, cannot hit back before being KOed. If SRs are up, all Slowbro needs is chip damage to be KOed, and this is Blaziken's best 'counter.'
You cannot argue for it having a 'legit counter' when you cannot even pass the standard for a basic counter.
Before coming up with hypothetical situations in which it can lose, remember this:
For all situations that involve outplaying the Blaziken user, the same courtesy should be given to the opponent.
Banded Azumarill fails to KO even with SR up in Sun.
>Assume SunYes, let's assume the conditions under which its usage is maximized. You could argue that Venusaur without sun isn't OU material, but that's a wasted point.
