These are different from the in-game wild card (the round's rotating wild number). A consumable Wild Card is a power-up you can activate: Pre-Game Wild Card — start a round with one wild already in your hand (costs 70 coins, or earned as a level reward). In-Game Wild Card — pull a wild from the deck at any moment during play (costs 100 coins). Use them when you're close to going out or trying to 3-star a tough Boss Level.
