Iyslander Specialization (You may only have Ice Eternal in your deck if your hero is Iyslander.)
Ice Fusion (As an additional cost to play Ice Eternal, you may reveal an Ice card from your hand.)
Create X Frostbite tokens under target hero's control. Then, if Ice Eternal was fused, deal arcane damage to that hero equal to the number of Frostbites they control.
