This and Bombarda both being in the set surprises me a little. With a four-colour deck vs a three-colour deck, these would be quite effective a lot of the time at locking out a certain colour. Are you and your wife fond of land destruction?

We're not overly fond of land destruction, no, but I thought one in each singleton deck was fine. I actually prefer land destruction in three- to five-color environments to punish good stuff decks from being too greedy with their mana bases. In a mono- or two-color format it's usually only good for stunting the opponent's growth and preventing them from being able to cast anything on time, which is just depressing.

I think the best use of land destruction is to destroy your five-color opponent's one white source out of seven lands so they have to get creative and rely on their other four colors, not to destroy your mono-green opponent's third forest on turn three so they can't ever catch up to you.

shrug Just my opinion on LD though. I know a lot of people have a knee-jerk reaction to their lands being destroyed and hate LD altogether. I just think it has a place in limited situations.
