Notes & Combos
Deck list I reached M5 with. Some notes:
-For as good and consistent the deck is, the two engines do not bridge between eachother aside from Beryl making the link-1. I added 2x piri reis map precisely because I saw too many hands that had no access to the BE engine.
-Ultimate fusion is a board breaker, interruption and a bonus target for wishes. Without the tyrant package, the deck is much worse in grind games.
-Master duel tax unfortunately limits your non engine options. Dominus purge + TTT would be excellent otherwise.
-Very minimalist extra deck aside from that. Crimson dragon, sfir, blazar etc are all slop win more garbage.
-Only additions worth making to the extra deck are Lightstorm dragon (when it gets added) and underworld goddess (deck can prevent towers, but can't out them).
