Mono R Madness Sideboard Help
Hello! I've been playing some mtgo leagues with a fairly stock Mono R list that I found online. I've realized I don't know how to sideboard all that well!
When playing against another mono R madness player, what would you bring in? I've been bringing in as many searing blazes as I can, but I'm unsure how many relic of progenitus to board in.
