This felt like a weapon that did not fit San Guo Sha 三国杀 the first time I saw it. Something just did not feel right about having an elemental component (frost/ice) in-built in a blade while being set in a semi-historical storyline. Till now, I still feel like this belongs in Final Fantasy more than Romance of Three Kingdoms. A search on the ownership of this blade in the story turned up nothing, which adds to my guess that this weapon was created purely for this card game. That's not to say that I am condemning this weapon to the trash bin. It may not be as dangerous as ZHU GE CROSSBOW 诸葛连弩 or as strategically useful as UNICORN BOW 麒麟弓, but it can still tip the scales when the need arises.
Attacking range: 2
When your ATTACK 杀 causes damage to your target, you can choose to prevent that damage by discarding any 2 cards of your choice from him or her.
Characters that match this weapon best:
Since the special ability of the FROST BLADE only works if your target is unable to DODGE 闪, it would be useful to characters who can forcefully cause damage with ATTACK, regardless of whether the target has DODGE cards or not. Therefore I would recommend this weapon for Huang Zhong 黄忠. The paradox to this is FROST BLADE only has an attacking range of 2, while Huang Zhong needs a weapon with as large an attacking range as possible to evoke his "Fearsome Archer 烈弓" ability. Therefore this weapon would be useful to Huang Zhong only if his health is sufficiently low, and the player intends to use strategic play to demolish cards instead of causing damage.
