1. Vanguard Slayer Vayne Reroll Comp Guide
Start with a Tier 5 Augment or aiming for 9 Innovators, especially with a lot of Recurve Bows.
Aim for Vayne 3-star at level 6 with 50 gold rerolls, also try for Last Whisper, Jarvan, and Senna 3-star.
Activate Anima Squad if Leona comes out quickly.
If you don't see Jarvan, Senna, or Last Whisper 3-star after Vayne 3-star, mix in Divine Invention (Renekton or Gragas).
Add Divine Invention at level 8, add Braum, Skarner (6 Vanguard) or Tahm Kench, Dr. Mundo (6 Slayer) at level 9.
If 6 synergy doesn't fit, add 5-cost value units or Sejuani (Fortress, Synergy).
