The timing resolution for simultaneous constant and triggered abilities holds true for prevent abilities as well. If a player has multiple different abilities that could prevent an effect that would resolve, constant ones take precedence over conditional ones and conflicting ones can be ordered by the player owning the abilities.
I have and installed and suffer 1 net damage. Can I choose to use Net Shield, or am I forced to use Guru Davinder and decide to pay 4 or trash him because his ability is constant versus Net Shield's paid ability? What if it was 1 meat damage and I had Guru Davinder and ? These are both constant, so what happens then?
|Yes, Guru Davinder prevents all net or meat damage, leaving nothing left for you to use the paid ability on. All simultaneous triggers on your cards are resolved in the order of your choosing.|
This ruling reverses the previous ruling in The Liberated Mind UFAQ.
