this is his video description by the way.
I don't play this in ranked, but if you know a good support it can actually work. I've got tons of experience playing bot-lane karthus and this is how quite a few of them turn out. Boosted animals don't know what to do when a wild mage appears in their lane.
not only are all those games played with and against low silver mmr players, but theyre all blind picks.
at least hes honest about it.
my point is, youre trying to contribute an argument to a discussion about the current bot lane meta, when its based on a couple non competitive games from a youtuber who doesnt even pretend that hes playing serious, and your own games on the bottom of the ranked ladder that is notorious for being a completely disorganized mess, in which you can make anything work.
