Ras Frosthwhisper OTK 2

COMBO:    Ras Frostwhisper + double Ethereal Augmerchant + double Lightning Bloom + Spellstone.

You can use the enchanter if you Reduce the total cost of your combo by 3 with Emperor. But the core combo does not need a cost reduction. You can deal 36 damage (41 with rune dagger boost) (81 with rune dagger and enchanter boost) in one turn. 

Drawing is the key here. You can replace drawing tools with your own choices. Sphere can filter your draws. 

Have fun!
