I'm curious, is Ishmaiah the Gibeonite's Negate an ongoing ability?  Or is it an instant ability?

Ishmaiah the Gibeonite: Draw X (limit 3). Negate special abilities on Evil Characters with toughness X or less. May band to a red O.T. Hero.
X = # of O.T. Heroes in battle

So say the band goes: Tribal Elder-Maharai-Ishmaiah-Heldai-Israelite Archer-Benaiah

Would this band negate characters with toughness 3 or less or with toughness 6 or less?

The draw is static because it is instant. The band is dynamic because it is an ongoing ability, it is constantly negating and checking.
