*shrug* creatures, artifacts and to a lesser extent enchantments get blown up so many times during the course of a game that i question whether a one-time deal like boros charm will matter. don't even mention planeswalkers as you're lucky if they stick in play for multiple turns.
my edh deckbuilding philosophy is when you're not playing blue, you shouldn't play too many reactionary cards. reverberate and wild ricochet are cute but you will still lose to the blue and even the black/green decks in terms of card advantage. you want cards that are proactive or actively disrupt your opponent's plan depending on your play group. marshal's anthem, scroll rack (with land tax), insurrection, blood moon, crackdown, rest in peace for graveyard hate and triggers like gravepact, shattering pulse for value, and so on.
as a boros themed edh deck, it gets a 6/10.
it's original ravnica block, time spiral block, 3x innistrad, 2x alara 1x conflux, your random favourite draft format. in that order.
