This 🔥ing card is garbage, cant even neglect enemy monster effect the turn when it summoned, only when the effect monster used it effect and got another effect on the enemy endphase. this card is worst than an N grade 🔥, just waste a slot on ur trap and spell
This doesn't stop Dakini because of the way thechain forms. Since Dakini is optional and Ruins is mandatory, Ruins is chain link 1 and Dakini is chain link 2. So Dakini resolves before Ruins can negate her effect. I think it would cancel her piercing effect, though.
