Pure Lyrilusc is arguably easier to play than Lyrilusc Tri-brigade, sacrificing some of the grind game potential to have more simple options for those wanting an easier, yet still viable deck to run. While the deck is a bit expensive due to demanding 3 Recital Starlings as well as a lot of SR rarity cards, it's cheap enough that you can rely on opening the secret pack they come from a few times to obtain the cards necessary, and craft whatever you still need.
Nerval exists in the deck as a searchable 1-of to make going into Bird of Sovereignty much easier to do, and going into a Stormwinds and/or Dark Simorgh can end games while on top of 2 more disruptions (Utopic Future Draco and Ensemble Robin), but can be taken out by preference. The deck can go 1st or 2nd very well with some minor tweaks to the deck to make one or the other better.
The side deck options are alternatives you can try out instead of some of the options in the main deck.
