Only if done poorly. Umori didn't have any meta impact at all, even in existing tribal decks. That value is not free, deckbuilding constraints are a thing. Again, they were too lenient with that for most of the companions, I'd agree with you there. But that's not an inherent aspect of the mechanic. They're also not even remotely comparable to OUAT, you don't get to pick which card you have. Nobody is calling the shitty draft tutors unacceptable design. If OUAT cantriped and tutored only for magnifying glass, it would not be an issue at all. Other stuff like that one mythic lesson was OP because they made it too powerful, but that doesn't mean every other lesson was terrible design.
