The remake of Water Spirit, sorta.

Edit: Correction to effect!

チューニングガム Chuuningu Gamu (Tuning Gum)

Level 1 DARK Fiend-Type Tuner Effect Monster

ATK 400

DEF 1200

You can only use the (1) effect of “Tuning Gum” once per turn.

(1) Target 1 face-up monster you control; that monster is treated as a Tuner this turn. During the turn this effect is activated, only Synchro Monsters you control can declare an attack.

(2) When a card or effect targets only 1 Synchro Monster you control: You can banish this card from the Graveyard; negate that activation.

Note: Tuning and Chewing sound similar in Japanese, so this card’s name is a pun.
