I am relatively new to Dice Throne, but I was interested in entering some of the local tournaments around me. I was told I would need three heroes to do so. I was also advised to have 1. The hero I wanna play 2. A S-tier hero as a ban bait, and 3. A hero that can cover bad mathcups/an all-rounder. I have the first two being Pale Lady as who I wanna play and Raveness as the S-tier. I'm not entirely sure who to bring as that third option. Also, who should I be looking out for to ban?
