Golden DON!!: Special gold versions, usually around 2 per 12-box case in newer sets
Winning 3 consecutive matches there will reward you with a random PROMO card that can be the Mario/Luigi Pikachu
Theres High MarketHigh Market, which has been in so many precons before now, it amazes me that it was forgotten here
Any card you think may have value should be stored in a protective sleeve and kept out of direct sunlight to preserve its condition
Being able to put creatures onto the battlefield for no mana allows you to keep resources up for the control elements, providing the deck with marvelous synergy
Of course, as I always say, a card is only as good as the context that surrounds it, so if there are not that many good fighting attackers, Barbaracle wont be as strong but I honestly think it is a fantastic option that immediately makes new fighting types a greater threat
