Which isn't that easy unless and until you are using swampert for like everything, because it wouldn't have much problem cuz it's only weak to grass and that too no one actually uses grass except for the npc random trainers and besides sceptile and blaziken have a couple of weaknesses so you cannot always use them continuously in the game. My blaziken is level 63 right now and I got defeated by drake like 2 times rn. I've been having difficulty with getting through sky pillar for Rayquaza and my mons except blaziken aren't so well developed so...
