With the wild imbalance in multicolor cards, I figured it'd be best to pare down each pair to 2 inclusions. This puts less strain on the limited fixing, and helps each pair focus on a plan.
Hardest changes were in , where I had to trim both Pernicious Deed and Life // Death in order to bring the count down to 2. Each has their own value to several strategies - Deed is a powerful boardwipe that has additional benefit in Enchantress decks, and Life // Death can double as both a reanimator card and a lands card. Ultimately, it came down to Squandered Resources and Cadaverous Bloom being too interesting to turn away from. If I had to reconsider, I'd swap Bloom for Life // Death, and I'll keep both of these cards in mind for future revisions.
Finally, Dismantling Blow, Orcish Lumberjack, and Tinder Wall have all ben shifted to their mono-color sections. Though the Lumberjack in particular isn't great without forests in play, and the other two are better when you care about the other color, they're all important role players that I don't want to count in the multicolor column, seeing as how the other cards in their original sections still have immense amounts of value to be had.
