"Oneiros, the Dream Mirror Tormentor" Rating Score by とき

Dark Neiros.
2 Dream Mirrors with different attributes fuse together to become light on the field.With 《Dream Mirror of Terror》, you can negate the activation of monster effects. Has a triggered instant effect that summons.
It will be fused with Tenma Neiros, which has the same material. Basically, this card leads to Tenma Neiros, so I want to put this one out. However, this card can't be powerful without the Dream Mirror Field, so if you don't have them, you'll have to bring out Tenma Neiros, which has an effect that completes itself.
With 《Dream Mirror of Terror》, you can negate the effect of a monster once per turn. You can simply set up interference with monster effects that you can freely use, and this card itself has a high ability. It's simple, but it's extremely powerful, and gives the Dream Mirror a commanding edge.
Furthermore, if you have 《Dream Mirror of Joy》, you can also do a Special Summon loop with Tenma Neiros. If you are targeted for removal, it will become Tenma, and if Tenma is destroyed, you can revive this card.
With this many cards, I feel like Dream Mirror can fight around fusion without being forced to move tricky, but it's a shame that it doesn't get rid of its reliance on the field.
