That's probably why WotC leaned towards Treasure: Gold allows you to double-dip in case some other effect requires you to tap permanents (because you can tap your Gold to pay for that other effect, and then still sacrifice the Gold for mana in the same turn)
Along with that, it also has Vigilance, Trample and Haste - which means it can not only attack the turn it comes in, but also defend even if it does attack
A cheap activated ability to grant lifelink ensures youll always have access to a lifegain trigger, too, making this 3-mana 5/5 great value, and overall one of the best mono-white commanders in the game
The gift set includes two collectible oversized foil cards and two playable foil game cards in addition to game token
