Wow! Champion is a powerful keyword. Probably a little too powerful for me to think is okay for real-life use, but neat in theory.
First thought. With Aragorn, why have a limit? As far as I can think,
Anduril, Flame of the West,
The Saga of Elendil, and
Ent Draught are the only vitality boosts in Movie Block (admittedly, I do not know Standard well but the new Anduril and
Ranger's Cloak are the only other ones I can think of).
Second thought: Why is Gandalf wielder of the White Staff if it is a hand weapon that gives him his bonuses? And is it each time you play a toil event (even if you don't exert for its cost?)
Nice ideas though!
