Player A attacks with a Deathly Wail, both player A and B have lost life. The attack deals damage etc. And we end up in the link step. Wording in rules section 7.0.7 seems to suggest you can activate or play action abilities wording 7.0.7=“…. cannot play action… except in the link phase”.
So back to the example, the chain has not closed, and player A wants to activate Grasp of the Arknight, and only pay 2 resources for it. Is that correct? Or should the chain be closed first (and thus create 2 runechants from Deathly Wail), and subsequently Grasp of the Arknight would cost 4?
And if its correct would this also work similar for Helm of Sharp Eye (when you reveal a non-attack action)?
Thank you for your assistance!
