What skyironsword means to suggest is that the card precognition serves either of two functions - to lower your effective deck size by a card or to show you your opponent's hand. In a deck such as this one, seeing your opponent's hand rarely changes the way you'll actually play, so it's not especially useful for that reason, and your deck size can be shrunk by a card by simply removing it.
(The nymph, on the other hand, is useful, since you'll often draw more than just one card from it).
As a recent light trialist, I love this deck. The power of Eternity and Crusader gives you especially strong control of the board. If you have upped Animate Weapons, I'd recommend using them, since you don't have to add any quanta types, but using the unupped ones is simply not worth it.
Your quanta balance might be a little off - changing your light pillars to time pendulums would probably be beneficial. Once the saders are in play, you'll be going through
at a pretty quick rate.
