I have two friends that have the game and one has the Promo Legacy from Gencon. Since we have the two decks can both Legacy play in a single game?
There’s technically a table-uniqueness rule, so while you could have both Legacy decks in play, their abilities and equipment will have to be highly focused. As discussed on another thread, you could do a house-rules thing and use both of them - you’d just have to watch out for multiple copies of things like Lead from the Front. It’s not considered balanced to use both of them, and you couldn’t do so in a tournament, but for the flavor of it in your own private games, feel free. 
Find two more friends and you can play with four Ras, heheheheh.
Gives new meaning to the term “Burn Deck”! …I’m truly sorry for that joke.
You will be! bans Adam from all Internet forums ever for bad jokes
Ouch, you might want to put some ointment on that, cause it was a pretty sick BURN!..I’m sorry too.
