Fridge is one of the 20 new cards added in Beta 6.6. Previous Versions can be found here.

This is a type of risk/reward card, as it give 5 health, but paralyzes the monster. Best used on cards that usually wont deal damage, like Pyrope or Ice, in addition to Taunt monsters such as Greater Dog in order to preserve their ability.

Fridge can also be used on enemy monsters, giving Patience a spell that paralyzes any monster of their choosing, but at the cost of prolonging the life of said monster. It's best used on an enemy that has its ability silenced in order to make sure it stays on the field longer without its effect.
