Wattuna →Used Deck

He's great on his own, but he's also a great target for 《Wattcobra》in your Deck.
Since there was no other decent card for Watt tuners, Watt tuners will be the card of choice from now on.
Level 4 doesn't mesh with the existing Synchro Monsters, but it's no problem because it gives you 《Wattkyuki》to call another Synchro.

A low class monster that will be a new fighting force for the Watt monster that appeared in the 12th term.
It has the ability to SS itself from the hand at the end of a damage sting in which one's own monster inflicts battle damage to the opponent, synergizing with "Wattgiraffe" and "Wattcobra", which have direct attack effects among Watt monsters.
In particular, Cobra has an effect that allows him to search for Watt monsters after damage calculations that deal battles damage with direct attacks, so you can deploy this monster as it is searched.
This card itself also has a direct attack effect and an effect that triggers when dealing battles damage due to a direct attack, and by releasing this card with Cobra, you can Special Summon Wattkyuki from the EX Deck.
And that Kyuki also has the effect of special summoning Wattchimera and Watthydra, which are Watt S monsters, with direct attack effects and battles damage trigger effects from direct attacks.
By connecting cobra → tuna → kyuuki → chimera, all four of them have a direct attack effect, so if they pass through, they will deal 1000 + 800 + 1600 + 1400 = 4800 battles damage to the opponent, and each attack will be reduced to 800. By increasing above, the damage will be added by 3200, and it will be just 8000 damage.
If it's 800 and all-strengthening, before Cobra attacks, you can send some kind of Thunder to her GY and use 《Solidarity》etc.
In addition, this card is also a "Thunder monster that self-SSs with effects activated in the hand", so it is also suitable for releasing to play "Thunder Dragon Colossus", and if you pass the turn to your opponent while standing "Wattchimera" etc. I'm very grateful to be able to do without it.
