Yeah I feel like your top end is too high. Especially with Boom//Bust and only 4 fetch lands. Have you considered trimming a few of those big spells for more board control? Geosurge can be fun but I feel like it’s too much of a trap. How do you plan against the average speed of the current meta? What match ups are positive or bad for your list?
There is one downside of sin prodder he probably needs to be replaced because if you don't get to 4 lands you lose and your opponent can make you exile those extra lands. There is probably something better at 3 or less now.
Sin Prodder doesn't really work that way since you can still draw a land under the card they flip. With 24 lands, that isn't a rare occurrence.
So before Salvation goes full Archived... If anyone would like please feel free to join the FB group I started and would like to build and expand more.
Flagstones of Trokair and Darksteel Citadel both are great if you want to cast the first half of Boom // Bust.
