One of the more obvious combos in the core set. Aragorn can ready after questing by spending a resource. Theodred can give a questing hero a resource. You trigger Theodred’s response to give Aragorn a resource. Then use it for Aragorn’s response to ready him. It works since responses all happen at the same time. This then let’s the first player choose the order the responses occur. In solo that will always be the player controlling Aragorn and Theodred. In higher player counts, generally will happen this way since the game is cooperative. That is unless someone is trying to grief the other players and makes it so it doesn’t work by reordering the effects.
