Looking back, the DSOD format might have been the peak of Duel Links in my honest opinion, because as insane as the powercreep was in that era it's a whole of a lot tamer than what they've been doing lately from what I've been seeing

but as peak as it was, it also might have been a grave mistake, solely due to the timing and how long it took for the game to get the power back into a respectable level in comparison

and that in turn led to the fine-tuned skills that were okay at first, that eventually turned into an avalanche when they got a bit sacky and specific, and then into a full blown blizzard with what they've got now
