Hmm... It's not really a good idea to make an exception only for 1 card, but what if the ability will not need targeting? As like:
I, Web: Next attacking airborne creature loses it's airborne ability (additive). Can be used multiple times per turn.
II, Web: Every airborne creature loses it's airborne ability. Lasts 1 turn.
And as you can see, there's a bit buffing on this ability. Coz, it's need it.
