I dont believe bard is like lurk for example where the two recommended regions are actually correct.
I think bard is slow value engine that requires buffing for value. Something like freijord or shurima have a far higher viability then Targon at the moment with the cards we've seen.
Looking at his stats when does bard "get good" at 2/5 that's terrible, at 3/6 still bad, at 4/7 now we're talking about a swing deck buffing engine.
So whether that's through 1 chime and a omen hawk, or the shurima landmark making bard a 4/5 with spellshield.
Eventually the math starts adding up, I don't think he will be top tier, I think he will be a better braum for the deck buffing archetype whatever that happens to look like.
With his universal region lock he can can even go in Ionia, for some of their hand buffing stuff, like the new bounce card.
Either way I like the design of here's a weird champ now make it work in whatever deck you want. Literally, any two regions, any cards, no restrictions at all.
Also, his "kit" isn't region locked either thanks to his wandering caretaker text, you're guaranteed his chime cards if you want them with 0 region restrictions. That's powerful.
