Water Fiend set. 4/??

[Thomas Wolf]

Some would say it's about "Swarming" I say it's about "Flooding" No set ID, because I don't really care about that as much this time.

 

As long as this card remains Face Up on the field, whenever a "Depth Demon" is Special Summoned under your control, your opponent must discard 1 Spell or Trap card. If your opponent has no Spell or Traps cards in their hand, you take 500 points of damage.

This card can attack your opponent directly. When it does so using this effect, any Battle Damage it inflicts becomes half it's orignal ATK. When this card destroys an opponent's monster by battle, Speacial Summon 1 "Depth Demon" from your Graveyard in face up defence possition.

This card cannot be Normal Summoned or Set. This card can only be Special Summoned by Tributing 3 WATER or Fiend type monsters you control. When this card destroys a monster by battle destroy all set Spell and Trap cards on the field. When this monster is destroyed by battle, destroy all cards on the field.
