Card Tips:There Can Be Only One
- This card can be searched by "Pharaonic Advent", "The Despair Uranus", and other generic searchers.
- This card can be combined with "Rivalry of Warlords", forming a lockdown in which both players will be allowed to control only one monster.
- This lock is capable of preventing a player from Special Summoning a "Kaiju" monster to their opponent's field (as long as the opponent controls a face-up monster).
- This card can be combined with "Zombie World", which turns all monsters on the field into Zombies; this card will force both players to keep only 1 of them and unable to Summon any other.
- This strategy can also be used with "Clockwork Night" to turn all monsters into Machines, or "DNA Surgery" for any desired Type.
