Serves a function at common. Boy does this make me miss the days of more liberally costed land destruction though. I immediately think of Pillage, which destroyed an artifact or land for 1RR at uncommon. Part of me wishes the cost of this was reduced by 1. Maybe 2BR?

We want to just throw multicolor around. I'm on board with this set being more multicolored in direction than the average with the general land theme and Discovery in particular, but this isn't a multicolor set.

I designed this as an interesting variation for the meh black kill spell at common slot, namely because we have lands that become quite powerful through DFC transformation.

Well, it definitely fills the "meh common kill spell" slot. :P Fair enough. I'd like to see what we can do for a more competitive land destruction slot or two.

Uncommon and rare is the place for that.
