Not so Brillant...not so Special...
But it works for me
=D
Maybe more will come

Levia's Tri-Lancer - I'm against beatsticks with good effects. I would take out the first ability and just use the second one, personally.

Levia's Spawn - You can't "tribute" a Spell or Trap Card, so this wording is sort of wonky.

Overall, I like the cards. Sea-Serpents really need more support, and a better defined theme than they currently have.

Thank you...I'll try to correct spawn

I hope you're aware that Levia-Knight won't bring back any monsters with an original level of 4. Legendary Ocean doesn't affect the graveyard.

Levia's Spawn, OCG needs a little work. "If you would activate the effect of a card that requires "Umi" to be sent to the graveyard as a cost, you can tribute this card instead of sending "Umi" to the graveyard."

I adore Ocean's Summoner's effect. Tri-lancer might be a little overpowered. Divine Vision might be a bit demanding.

Overall, I like these.
