Ceremonial Knife⁣ - Innistrad: Crimson Vow⁣ (Common)⁣ [254]

Ceremonial Knife is a low-cost equipment that gives the creature it's attached to a +1/+0 boost in power and the ability to create a Blood token whenever it successfully deals combat damage. Blood tokens are versatile artifacts that allow you to pay one mana and tap them to discard a card, then sacrifice the token to draw a new card, effectively letting you filter your hand. This card is particularly useful in aggressive strategies where you want to get in damage consistently, but its downside is that you need to spend extra mana to attach it to a creature, making it less effective if you’re not already set up to deal damage right away.
