Start: Rag, Eudora, Tirion
Bench: Thrall, Voljin, Sylvanas

Rank 1 EU, 70-18 with this comp. Imo the most versastile one right now. Highly favored vs triple green/frost and vs Xuen/Longxin builds. GVT and Rag/Geddon are a bit tougher.
Not to worry when the starting 3 all die and opponent has 4-5 mercs left. The Bench is nuts when timed well. Hf 🙂
