...Okay so basically all you do... Is card draw.

You are looking to get all direct damage into your hand at turn 10 along with Sorcerer's Apprenticex2 and one Kobold Geomancer

This combo can be done at turn 8 without the Kobold but will only do 26 damage with all spells.

The hand you are looking for at turn 10:
Fireballx2
Frostboltx2
Sorcerer's Apprenticex2
Ice Lancex2
Kobold Geomancerx1
Playing all these cards turn 10 will result in exactly 10 mana.

How to play:
You try to get all the card draw you can get to set up your combo, Stop damage from coming in by clearing the board with your Blizzards or stalling by using Frost Nova.

You can delay even longer with the Ice Block+Alexstrasza combo when you are low on health.

Doomsayer is useful to either wipe a board and delay a turn or in combo with Frost Nova to completely waste the opponents turn.

Leper Gnomex2 is in the deck in case you need the 4 extra damage from their deathrattle. Like i said, the combo at 8 mana without the spellpower only does 26 damage. Meaning, with the two leper gnome deathrattles, they will be at 26 health.

Bad Match Ups:

Bad match-ups may include: Control warrior and control druid. As far as other match-ups, it's mostly up to RNG of the cards and surviving for your combo.

GOOD LUCK HAVE FUN!
