The intent of this form of particle is to introduce more customization and flashiness that ISN'T more hat/taunt unusuals effects, something that we have in abundance.

Ideally yes, Valve would implement this submission with a Smissmas restriction, mirroring a Spell's Halloween restriction.

That is entirely up to Valve’s choice, we workshoppers do not control how an item is implemented. It could be through unboxing, contract rewards, MVM missions, a free gift, who knows!

This Miracle replaces the muzzle flashes of all applicable weapons with a new winter counterpart. In addition, it changes the Huo-Long Heater's fire rings for consistency.
