Just like iancudorinmarian said, it's just a deck for fun, though I usually win every battle in the Elements trainer with it, so it might be a good, powerful deck if you could assemble it in Elements.
As for those of you who are questioning why I have the other random shards such as Shard of Sacrifice or Shard of Void: when I made the deck, it consisted of 15 Quantum Pillars and 6 Shards of Serendipity and I had 9 more spaces to fill until I could go to the Menu to test it out, so I just picked some random Shards which I thought were best. Really, you can replace all the Shards but the Shards of Serendipity with whatever you.
For those of you who are wondering why I put so many Quantum Pillars in, it's to guarantee that you'll actually get the Quantum you need to summon out the Shards and the cards that you get from the Shards of Serendipity.
And THEACCUSO, the Fate Eggs are a great idea!
When you say, ''win every battle'', do you mean False Gods?
Woops. I should be more specific. If I get reeeeeeeeeeeally lucky, I may win against a level 4, but this deck can't stand the power of a False God. But it 98% of the time wins against level 0, 1, 2 and 3.
