Spartan Serpent

[Atypical-Abbie]

WATER based Decks are normally not known for using Flip monsters, so I figured I would give them a strong Flip monster that is also pretty easy to Summon for them. You can use this in other Decks as well, and it has a quite powerful effect to boot, along with good stats, and is able to re-set itself as well. You get to return 2 of your opponent's cards should they decide to attack this, or if you force them to with other effects.

 

FLIP: You can target 1 face-up card your opponent controls; return that target to the hand.
You can discard 1 WATER monster OR 2 monsters with different names; Special Summon this card from your hand in face-down Defense Position. If this card is flipped face-up by your opponent's attack, return the attacking monster to the hand at the end of the Damage Step. During the End Phase: You can discard 1 monster; change this card to face-down Defense Position, then if you discarded a WATER monster, draw1 card. You can only use each effect of "Spartan Serpent" once per turn.

While it is easy to Summon, it's also expensive to do so, unless you are running floaty cards or Atlanteans. And as a Flip it is inherently slow. Really, this would be played as an enabler for Atlanteans at best, and even then, I suspect they already have the tools to go off without needing this, but IDK for sure since I'm not an Atlantean/Mermail expert.
