What is a Combo Deck in MTG?

Combo decks win by assembling a specific combination of cards that creates an infinite loop or an unstoppable win condition. They use tutors and card selection to find combo pieces consistently. Classic combos include Splinter Twin, Thassa's Oracle + Demonic Consultation, and Underworld Breach.
