Card Tips:Royal Swamp Eel
- This card can be special summoned by Superancient Deepsea King Coelacanth's effect, and if done so, you can even Synchro Summon two level eight monsters with his effect alone (if you summon two of Royal Swamp Eel and two other level four Fish monsters with his effect). Even better, if summoned by Coelacanth's effect, the effect of Royal Swamp Eel will be negated, allowing you to use monsters other than Fish for the Synchro Summon.
