The immortal Dawn Serpent is a fun tool for Yan Lo to use. Combine him with Toshiro and you have a pretty powerful minion. as tomjoad said, Lightning Dance. Swear by it, Live by it, Dance your opponent squishy models in the clutches of your scary models. Yan Lo with both Spirit and Bone Ascendant can live suprisngly long. Misdirection is a great upgrade, as is Fortify Spirit, which I have found new respect for. Reliqunary I take when i have 2-3 Ancestors, for only 1 it usually isn't worth it. Finally, you can take Onryo in your crew, which give you access to Adversary, which any model can benefit from if you time Transcendance right. Spirit Jorogumo with Armour +2? that is pretty sweet.
