Snowdrake's Mom is a good all-rounder card for its price. It can be deployed early/mid game but can also be saved for later in game to paralyse more powerful monster with its ability to paralyze 2 random enemy monsters.

This makes it useful in any deck, particularly Patience and Determination. However, while it has a decent ability, it also has a cost of 7G with low stats of 4/4, making it less useful against Perseverance and Justice decks, especially against those whose decks mostly exists of spell cards.
