How does the Varudras work there against the fountain? it says negate the activation, not destroy. Has to detach a second card to destroy card on the field. Why was only 1 card detached and the fountain sent to grave?
If a field spell's activation is negated, it automatically goes to the gy as its activation wasn't resolved correctly. This is different from "negating an effect on activation" of a field spell: for example, if you use Ash on Perlereino, the field spell will still remain on the field as it was still successfully activated: however, if you negate the activation of Perlereino with something like Varudras, Perlereino won't add and will go to the GY (because its activation didn't resolve correctly, therefore it didn't activate and thus there is not anymore the condition for it to add. Obviously it will also go the GY for the aforementioned reason).
@duonglong7171 he did it literally a second before he didn't forget lol. That skill drain was literally used the next turn. That's a skill drain that shouldn't be there
