I'm toying with the possibility of a tri-color burn deck, in Mardu colors. I like the things that the white splash and the black splash have to offer sooooo yep. Firstly, what do you guys think would be the ideal set of land-counts for this deck? I'm familiar with the option available but unsure about what numbers of each to use. Fetches and shocks of some varieties? Blackcleave cliffs perhaps... The splashes seem to be ok, although of course the lands will hurt a LOT in the mirror. Which leads to my second question, does this deck seem decently competitive for local modern events?
