Original card: Eria the Water Charmer
Face-up monsters your opponent controls become WATER. You can Special Summon this card (from your hand or Deck) by sending 1 WATER monster from your hand or field to the Graveyard while you have "Eria the Water Charmer" on your field or in your Graveyard. You can only Special Summon "Eria the Torrent Charmer" once per turn this way. If Summoned this way, this card gains these effects.
● WATER monsters you control are unaffected by your opponent's WATER monsters' effects.
● Once per turn: You can target 1 face-up WATER monster your opponent controls; take control of it until the end of your opponent's turn.
