Notes & Combos

As a returnee in master duel I've enjoyed playing mathmech in this meta. Also I prefer droplet over imperm because most of the meta decks are playing in your turn.

This decks consistently now have conflict in your endboard and thats why i dont play @ignister wizard cause most of the time I get micro coder for combo.

If you have any suggestions or any comments on my deck feel free to comment as I am trying to push for master I as I've enjoyed playing this deck again.
