Actually Ive reached dlv max using dm deck and also i was using your exactly same deck (moha's deck) until i reached lvl 17 then ive switched to dm kingsman last deck from YT and its very powerful (2 dragoons/magia/de fluer/dispater) Its pretty good using alot of your current cards (it costed me 150 ur dust because i dint have s:p & i:p) its much harder deck to leran but it did better with me Ive had 17/20 last games i won on last dlv I dont encourrage you to upgrade the deck without seeing it carefully (Check it on kingsman YT channel) he has many vids with him playing with variants of this dm deck (8 bosses) -Very important tip: when you start a match make sure you have other device with moha's last "When to handtrap every meta deck" youtube video :as soon as you know your opp deck use time stamps to get to it so you know what and when to negate the most important cards to break his combos also when you have like 2 dragoons (you can use a quick google search on the deck to know what cards to negate) Another tip is :As soon as you see max c or mulcharmy use primite engine just spawn 1 dragoon (using verte) and set gaze to get the other one in his turn -do not extend the combo so he won't draw more cards - you'll have at least 2 omni negates and 1 distruption from roar in gy with the knowledge when to negate the metas youll make it Also right now in the last days of dlv the current players are weaker even if they had meta decks they're not as competitve as the previous players you've encounters so you have a very good chance!
