I like people complaining about dm decks (tier 3 based on dlm) when there are obviously more powerful decks. I am certain that KCup will have 0 dm decks in the top 4 list. We have never seen a dm deck winning a KCup. All we see are shiranuis, heroes, elemental sabers. Why? Because they never brick and can make a comeback. If DM deck doent win in the first 3 turns then it will most likely loose.
Ofc, since it is a deck that has an answer for everything: free canadias/spell-trap negation monsters/utilizes 100% invoker/runs tons of meta traps etc etc. Even their palace field is never a dead draw or brick (unlike the 99% of field cards) since its a basicaly a monster searcher. But yeah, kids still consider dm as a proplem in our meta...
I think most complain about DM is because they have a turn 1 play that's almost not possible to beat unless you draw the answers on you starting hand. That set navigation with circle on feild and a DM in the hand.
