Forum:Cyber Dragon Infinity effects VS Oblisk The Tormentor

How would the effects resolve, This is how I interpret it, Oblisk Cannot be targeted by CDI first ability, so it would be

OBLISK(When Normal Summoned, cards and effects cannot be activated. Cannot be targeted by Spells, Traps, or card effects.) VS CDI(You can target 1 face-up Attack Position monster on the field; attach it to this card as a face-up Xyz Material.) which means CDI could not use its first effect against oblisk, because its is trying to target it. but if Oblisk used his first ability, could CDI counter it with its second? which reads, CDI(Once per turn, during either player's turn, when a card or effect is activated: You can detach 1 Xyz Material from this card; negate the activation, and if you do, destroy it.) In the text for CDI it does not mention targeting, just negate the activation and thus destroying it.

how would you interpret these two cards effects versus one another? AAABIAKKKK (talk • contribs) 01:47, December 13, 2016 (UTC)
