Red-Eyes decks are centered around their boss monster, Red-Eyes Slash Dragon, with high ATK and the ability to protect your cards while you control an equip card. The main way to make Slash is with Red-Eyes Fusion, which can also send fusion materials from the deck. One popular support card is Black Metal Dragon, which can immediately be equipped to Slash and searches for another Fusion when sent to the graveyard. Red-Eyes can inherently deal with large ATK monsters because of the boosts to Slash, but sometimes struggles against defensive traps without cards like Cosmic Cyclone to help clear the way for attacks.
