for sunburst decks

Came across this in the .exe file on the never-ending search to override card frames (still no luck on that front
): ignoreCmcOver.
Apparently if you set that attribute to 1 as part of your LandConfig tag, that bypasses the automatically calculated land insertions and puts a flat amount of each type of basic land in, which you can then play around with using minPlains, minIsland, etc. Not terribly useful for decks that don't want at least one of each type of basic land, as it doesn't appear you can have less than one of each. But for those building Sunburst-type decks, you don't have to include all five colors of spells if you don't want now.
