Don't Know what to side with and 40 isn't always good I have a good 50 and 45 Galaxy photon deck irl and in dn. And usually I like putting anti-meta side decks but so many can interfeer. So what 5 cards I should take out and what cards should be in my sidedecks?
I haven't experimented with the deck yet, so I cannot give you clear suggestions on what you could do, so drop what makes it inconsistent. Powerful combos which can create advantage is ideal with how the game is currently and you should go for that, but if it is inconsistent just leave it alone.
