Comet Storm

I don't even use Fireball anymore because of this card. Put 3-4 mana into X and kick it 3-4 times. Poof, you can nuke several targets like Fireball but for less mana because you don't have that "Pay an additional 1 for each target beyond the first" crap. Or just simply hit them for an easy 10+ damage directly.

Fireball Just got a MASSIVE upgrade.

This card is awesome in the late game, and provided you can sink enough mana into it, it literally becomes a one-sided board sweeper.
That said, late game is about the only time you'd ever want to draw this, because otherwise it's just an over costed burn spell. Hitting two creatures and a player for 3 damage each would cost you seven mana in total.

Pulled two of these in the only fat pack I bought for this set. Glad I did because that was the only time I bought anything from Worldwake. I'm not the biggest fan of playing burn, but this card has definately won my heart over, especially in free-for-alls. Nothing is more satisfying than nuking every single opponent with one card, and this is the card to do it with.
