My advice, after playing Sylavaneth for over a year now, is once you have decided on a list to try - stick with it. There are so many rules, interactions and strategies you can use within Sylvaneth that you’ll need to play a few games to learn everything. Keep reading the book, after each game - re-read it. There will be rules you forget or play wrong (I still find this is true for me too)
Sylvaneth is such a cool army to play. I genuinely get really excited to see it is still attracting new players.
Welcome along!
