Torbran makes the burn and aggro creatures hit harder. There's some cool plays like 3rd turn Chandra, Fire of Kaladesh. 4th turn ping with Chandra, play Torbran, ping again for 3, flip, hit for 4. Chandra, Pyromaster can Searing Blaze while Torbran is out.
Firey Confluence can be 12 damage while Torbran it out. Manabarbs can be really mean too and don't be afraid to mess with their lands cause it's fun to make people feel bad and not wanna play you.
