Balance is toast, Blue eyes probably toast due to usage, also Trimid might get a nerf as well due to doing well in the top 100.
Onomatoplay is not long for this world.
witchcrafters also got a good spot in the kc, imagine konami nerfing the deck to oblivion and for the final nail in their coffin konami nerfs balance too
The whole point is that this ISN'T the TCG. So these comparisons are pointless. If I wanted to deal with all that slow play and all those people who don't shower just to annoy opponents I would play the TCG instead.
Where there's forty card decks and main phase 2 among other things. I'd say there's a big difference. The TCG also does have a separate speed duel format too though where they have skills from what I understand.
