"Penguin Ninja" Rating Score by みめっと

In fact, as a reverse effect monster, it is a Penguin monster that belongs to Ninja for the first time since Pensol.
Penguin Nightmare is not a Reverse Effect Monster, it just has an effect that activates when reversed.
The effect is the Spell Trap version of Pensol, which allows you to peel off multiple backs at once, but unlike Pensol, you can't bounce cards on your field, so you can't reuse Continuous Spells and Field Spells that have effects when activated. It can't be done, and it's a Spell Trap that returns it, so it's an effect with a lower advantage acquisition ability than Pensol, which can return EX monsters.
This is where you want to use it together with the effect of Nopenguin and remove it instead of bouncing it.
In addition, it has the effect of putting Penguin monsters to sleep every turn, which makes it possible to use the effect when reversed again, especially if there is a set monster, you can SS yourself and wake up the set monster immediately (Penguin Squire). The compatibility with is outstanding.
You can also specify yourself and put it to sleep, so if you can keep it on the field, you can use the reverse effect every turn. Opponents will find it difficult to use his spell cards.
The status is higher than Pensol, and it's a pretty strong monster once the Deck starts spinning, but I have the impression that the scenes and opponents where it can be used effectively are somewhat limited compared to Pensol.
