I've removed Thunderous Wrath because because I hate that card when I've got in the opening hand. I've added one more Mountain because a lot of times i'm opening with only 1 land.

I've modified the sideboard, where I live there are a lot of Splinter Twin and Tron. So I'm playing 4x Molten Rain, 4x Smash to Smithereens against Tron. 3x Combust against Deceiver Exarch. I'm thinking to put 2x Ball Lightning on sideboard against Leyline of Sanctity. Guerrilla Tactics are good cards against Jund but I'm not sure if they are useful.
