only ______ attacks may be used agains ____ for remainder of battle

[breadmaster]

suppose i play an AE or a doubleshot attack that has 2 icons

can it be defended with the CD specials, if one of the icons in the attack corresponds to the CD?

AE: "Act as a 4F, combine with a S for single attack."

Single attacks combine the property of both cards. So the 'attack' is now a Fighting AND Strength so:

Blocking with a CD that says only S attacks: Then yes, it would block because it the attack is F and S.
Blocking with a CD that says only F attacks: same thing.

Hypothetically, the only time the attack couldn't be avoided with a CD would be a ones that say "attacks made with {x}" with {x} being Special/Power cards. Such CD cards do not exist (only Universe cards exist).
