The player said that his biggest problem is that his build is a brick-fest, so much so that he decided that Desires was worth playing whilst only playing 1 copy of Big Dipper and playing Foolish Burial Goods even though it's semi-limited in the OCG.
It's also cool that he's playing 11 non-engine + 1 Gameciel and 2 Desires. This is probably the highest amount of non-engine that you can play and we should keep this in mind when building our own decks
There are also very few ways to summon Baronne, you're mostly looking at normal summoning Ash and Maxx C, with the Normal Summon completely free it give you free range to use the WATER Barrier Statue.
This is definitely a midrange deck and I assume that Radiation is searched regularly as the Extra Deck is quite bare
There are 21 copies of lv7 or higher monsters which means the majority of the time the Mikpolar variation of the Alpha Radiation Combo will not be live so the original player must be okay with sitting on Septentrion + BoM + Dipper + a hand-trap of some kind for a first-turn play. This means he probably does not lean into turn 0 interaction and this might be because he doesn't value MST or D.D Crow that highly in many matchups.
