Firstly, Merry Xmas all.

I'm playing my xmas present with my family and was wondering on this:

Can cards with a Marshalling effect use those effects the same turn they are Marshalled, or do I have to wait until the next Marshalling phase?

Ex: if I play Hall of Heroes during my Marshalling phase, can I then immediately kneel it to reduce the cost of Marshalling Ser Illyn Payne by 2? And having done so, can I then immediately kneel Ser Payne to kill an opposing character with STR 2 or less?

Thanks,

Mo

They can be used the same turn that they come out

Thank you Venters. Merry Xmas
