In a recent game a player tried to use Seige of Darkness, then use no matter the cost to reduce Doctor Voodoo’s spender to 0 and make it eligible for SoD. We ruled that because No matter the cost specifies an attack ACTION, that no matter the cost could not be played make spenders available for SoD.
I have 2 questions.
Does No Matter the Cost require an attack ACTION to be declared?
Do Seige of Darkness and Wakanda Forever attacks need to have a printed cost of 0 or do reductions make higher cost attacks viable?
