In my review of Shishizaru's art, I mentioned this card for its great art. What I failed to mention was this card is also awesome. It's main awesomeness comes from the word "sacrifice". This gets around 2 major sticking points with certain permanents: indestructibility and regeneration. Day of Judgement and its kin allows for regeneration whilst Wrath of God and co. don't hit Indestructible things. This card sends both Thrun, the Last Troll and Darksteel Gargoyle to the graveyard with the same swipe. Now, this card does cost 6, is at sorcery speed, and allows for choice for your opponents. However, the last point is outweighed by the fact that by turn 6 your opponents will probably have a hard time picking with 3 things to save since they'll be losing at least 3 lands (if they don't care about what's on their field) and considering Rain of Salt also costs 6, I think it's definitely worth it.
Pros: Hits Indestructible and regenerating permanents
Cons: Pricey, allows for choice
