True, but isn't that true with pretty much every upgraded card? I mean, if elite otys were allowed, everybody would use them simply because they would then have a leg up on the other cards.
So yes, I guess you're right in unupped format. But in the pvp "metagame", as in pro duels in general (not just in tournaments), most matches are played using upgraded cards. So SoG is not "the" card to have in a deck for a normal metagame duel. In unupgraded tournaments, yes, it may be the card to have. But I hardly consider this tournament to be metagame

.
And I advocate banning SoG from unupgraded tournaments such as this one was in the future.
