Are you sure it's very effective?
Here's some criticism if you want.
3 Pendulums is too unreliable for 15 entropy quanta. If you draw none in your hand, you will be outrushed by almost any deck. If you draw one, it will still take too long to play enough discords, especially with 4 precognitions to make you draw even more discords that you don't have the quanta to play. 6 discords is too much. Discord loses a lot of its effectiveness after you already have one in play. And it's a terrible attacker against rainbows, which are common in upped PvP. 2 cards and 4 quanta is not worth an upgraded creature with only 6 attack. Just 1 black hole isn't enough because they are amazing cards with discord and the quanta to play them. You have both, so why only one black hole? Poseidon needs 2 supernovas, and its effectiveness will be lessened because you might draw it too late in the game. 4 precogs are too much, especially when you badly need the quanta from your mark and pendulums. There are 10 weapons, which makes 2-3 of them useless. You have no use of air quanta, so I would upgrade 2-4 of the animate weapons. Flying arsenic is too slow with little stalling, especially against rainbow and immo.
