So I know you mean this more subtly than the typical MTGS line about such things, but I still think the following are true: the argument both acknowledges that the cards are rarely beaten and are miserable when not beaten, and doesn't really care about that. It also leads pretty quickly to including cards that are even more 'unbeatable,' which is a worse experience. Whatup

One thing we do on here is make Cubes which include, on average, cards far 'worse' than a typical Powered Cube, but decks that are much, much better -- they're not defined by a single card so much as the interactions of 20+ spells and some sweet lands, so we're not beating a single card so much as beating another clump of interactions. Subgames within games are sweet, but what if the game is just the subgame? I guess I throw in Jitte with other GRBS, and GRBS just makes me tilt more so than anything else. When I beat these cards, the feeling is way closer to 'thank god this game wasn't quite ruined' than 'lookit me I got lucky at da club,' the pleasure is, like drubbing an ill-tempered otaku at a PTQ, or the moments of happiness in Ada's anxious life, mainly the absence of a baseline negative feeling than it is an intensifying of our typical Joy of Cube.
Of course, some of every Cube's cards are better than others, and your experience may be completely different.
