is Yogg competitively playable in any real way? I don't follow competitive play, but it seems really bad for that. if it's not then I think massive swinginess is fine for the fun factor. if it is, though, then yeah, maybe.
He has had shown up in tournaments and at least one tournament has come down to him in the final two games of the final match, used by opposite players. He may not be the most consistent thing ever, but if he never sees another competitive deck (unlikely) he has already made his mark by winning a non-negligible number of tournament games.
Edit:
Oh and Tempostorm claims Yogg Druid is number 3 deck atm.

Hearthstone is a game struggling to be an Esport, where the "pros" constantly get asked why they get knocked out of tournaments and the response goes something like "The other person got luckier." It has a huge problem with players **** on the game by.... well basically telling the truth but in the most negative light possible. And whether it deserves the reputation or not, it is not viewed as a "real" esport compared to things like CS:GO, LOL, etc, because rng cards like Imp-losion and Dr. Boom play a huge role in who wins games at the most competitive level. Thus the on-and-off debate about Yogg Saron. While it's an extremely entertaining card, when thousands of dollars in prize money are decided by something like Yogg Saron, it's very hard for people to take Hearthstone seriously. It has at a minimum furthered a stereotype/stigma people have been trying to get disassociated from Hearthstone.

Mana screw ruins just as many games of Magic, but people find a way to make it a competitive game anyway. Card games are sometimes decided by luck -- that's just the nature of the beast.
While this is true, Magic has over the years tried very hard to limit the number of random swing effects, and it is a better game for it, while Hearthstone repeatedly **** all over MTG design philosophy when it comes to what is good card design and what isn't. I do not buy the argument that it is better for the game to be decided by
added rng on the cards themselves, when they went through all the trouble to remove as much as possible from things like the mana base.
