Mudragon of the Swamp is also useful for recycling your Fusion Monsters as it could be Fusion Summoned by using Tearlaments monster (DARK Aqua) graveyard effect with El Shaddoll Winda (DARK Spellcaster), Grapha, Dragon Overlord of Dark World (DARK Fiend) or Predaplant Dragostapelia (DARK Plant), and thus returning them to the Deck and Extra Deck
