Impulse⁣ - Dominaria United⁣ (Common)⁣ [55]

Impulse allows you to look at the top four cards of your library, letting you select one to add to your hand while placing the others at the bottom in any order. This card enhances your card selection and helps you dig for key pieces in blue control or combo decks. Its low mana cost makes it easy to fit into various strategies, but it doesn't provide immediate card advantage since it only nets one card.
