Blue-Eyes Structure Text
Activate this card by targeting 1 Effect Monster on the field; its effects are negated, also it cannot attack. When it is destroyed, destroy this card.
● This effect only negates while that target remains face-up on the field (much like "Skill Drain").
● If this card targets an attacking monster, that monster is still an attacking monster until this resolves.
Therefore, if this card is chained to "Dimensional Prison", targeting the attacking monster,
that attacking monster is still banished.
