Can you active ate {
Duskmantle Guildmage} first ability anytime or do you have to activate it before any card went to the graveyard to deal the life loss?

The ability creates a delayred trigger which once activated will trigger obly when cards go to the graveyard. Only after the ability has been activated will it start counting cards that go to the graveyard.
