Blizzard is the best build period nothing is going to be better for you on a ladder reset. Meteor orb is slow in comparison. Just level the normal way it's unironically the fastest through a day 1 ladder reset, Nova into Blizzard. All you need is to shop for a lower res wand and it's a easy mode. Just find a reset team be the tele sorc than after the campaign is finished, you just farm hell ancient tunnels and meph ez mode early ladder wealth.
