Magic: the Puzzling

This isn't really related to manalink, but I thought you guys might have some fun with this puzzle I created. Who will be the first to solve it?
It’s winter time and your adventure-seeking band of Goblins are out to have a fun day of sledding and skiing. Your opponent, Old Man Winter, has other plans for you. Attempting to plow you under with snow and keep you in your burrows, he has subjected you to an unending barrage of Ice Storms, Ice Falls, and even Avalanches! He currently sits comfortably in his Glacial Fortress, knowing that he’s protected by his giant walls of ice, and the Flashfreeze in his hand that he has boastfully revealed. To top it all off, he has an Ice Cauldron ready to untap and deal you the final blow with Icequake on one of your now-snow lands. Can your team of goblins with shovels get rid of enough snow to destroy Old Man Winter before he gets to untap his Ice Cauldron?
It is your first main phase.
