yugioh mystic swordsman deck LV4 Konami by sending this card to the Graveyard Yugioh Flame Swordsman Deck -

Friedrich, a student at MU, was not as fortunate

Famous examples include the Legendary Dragons (could fuse with anything of a certain category to create a new monster with varied effects), Neo Galaxy-Eyes Tachyon Dragon (could "time travel" by reverting the gamestate), The Seal of Orichalcos (allows a player to put Monsters in the Spell/Trap Zone), Supreme King Z-Arc (counted as Fusion, Synchro, Xyz, and Pendulum simultaneously), and the Meklord Emperors (consisted of five monsters summoned simultaneously to make a whole)

Hopefully this gives you an idea how packed the mana base is in this deck

When the Level of this card increases, inflict 400 damage to your opponent
