I want to keep it a max of 33 card deck. If playing with frodo, I have to make room for
hobbit sword or antiswarm stuff, while Boromir can boost strenght and wear armor in case needed.
Yes its true Boromir RB sucks, but that's why Aragorn can take up to 3 minions and then cancel with
Boromir's gauntlets.
Notice this situation (2 companions) is the only situation in which Boromir RB is more playable than Isildur, so I guess the suggestion by Decipher was that Boromir RB was to travel with very few company.
Also, it's good to put at least 2 tokens on
Noble Leaders and since Boromir can be forced to fight sometimes; he can be wounded twice.
Ring of Barahir, and
Athelas can heal him.
Although the principle here is that you don't give as much twilight so anyway Boromir will never fight.
Maybe this would be easy to kill for an arquery deck but I don't think swarm, uruks or nazgul will have it easy.
