Serves you right for choosing the worst starter
But still, situations like that are pretty interesting, even if there's only a 1 in 3 chance of them happening. I still remember the difficulty of facing Brock in Red/Blue if you started with Charmander.
He clearly chose the best starter.
But I wouldn't say sun/moon were easy. I mean with the way I played it was more difficult to the point where I got rekt by an alolan raichu due to being under levelled. But I will say that a nuzlocke of sun and moon is something that will be hard especially US/UM. There are multiple totem pokemon that come to mind that will in fact kill you unless you overlevel. The grass one stands out, mimikyu could do it. And in US/UM the dragon psuedo legend... who I was multiple levels higher than surprised me when it took a moon blast due to its item then proceeded to destroy my team actually forcing me to use items. ORAS is the worst remake of a pokemon game hands down and it is too easy. But you wont have the problem with sun and moon, i've seen people do them... the majority fail, pretty early on.
