Quick question from someone saving up for Dead Reckoning--can I substitute Lighting Storm for Hailstorm and still get by? Obviously it misses a few important targets that HS hits, but 2 or 3 damage should still be be enough to rinse mist aggro, I think.
Lightning Storm might be okay in the market. There are quite a few anti-aggro tools in the deck: Vara, Rindra's Choice, Torch, Annihilate, Permafrost, even snowballs from Jotun Hurler. I'm not sure I ever pulled Hailstorm from the market, so a different tool like Statuary Maiden, Molot & Nakova or Black-Sky Harbinger could be good.
