3:22 i never got a Licki in gen 1 so it's new to me seeing the player perspective sprite for it. Actually kinda wild how angery it is :like "grrrrr dont mess with me or your gonna get slobbed!" :p
The only thing Lickitung has going for it is that it’s easier to obtain, being a guaranteed in game trade. Tauros are notoriously hard to find in the safari zone, only appearing 1 percent of the time.
Wigglytuff being on this first list is a bit of a misunderstanding of when it shows up: After Brock. You have this new Bide TM and they give you a mon who can take massive hits and bide it back. It's a counterpoint to Onix, another mon meant to fill a specific niche in this pet-based RPG around the same time: A wall to the mostly-normal types you've collected so far, so you learn that even Ember is better against Onix than Hyper Fang. This is why Butterfree is a great Brock counter: it's rock weakness isn't meant to be a factor because Brock is there to wall normal types. It's HP stat is so low because Bide has to be challenging without being dominating at level 12. Most of the poison types are the same, being the primary type of the Team Rocket enemies. Weezing and Muk (and Zubat) have "mixed defenses" so that 8 year olds have to juggle multiple kinds of pokemon, or at the very least multiple moves. Grass types being a status-type, akin to an enchanter or crowd control warlock in a traditional fantasy RPG, are still poorly balanced to this day because of that role.
On the whole, this seems to be a video that understands that RBY were more RPG-like than later gens, but doesn't actually consider what RPG-mechanics would be for children in an era before online walkthroughs.
Brother, Double Team is aeons better as an accuracy alteration move. Just because Flash is an HM is not nearly enough to justify its inclusion in the list.
Flash forces your opponent to switch out, sure, but Double Team keeps your momentum. The fact that the opponent can't do anything to defeat you other than using moves that don't miss at all (which are rare) or going through a hit check every time is way more useful than "forcing" a switch.
This is why abilities like Moody are banned. Your opponent loses all agency and just has to pray to RNG. Unless you decide to switch (which most people at max evasion won't do).
Solar Beam was such a let down in gen 1, they hyped it up so much in the anime but in the first games it is completely out classed by razor leaf's critical hit mechanic. Solar Beam fans at least got a good Venusaur card in the tcg and by gen 2 they made it better with sunny day and made razor leaf less op
