The card is a bit clunkily worded, but in essence, it basically splits each player's creatures into two sides of the battlefield (or the "river")
This makes it more likely that another effect (such as that of March of the Machines) will make those artifact Auras into creatures
6 mana is a lot to ask for a mana doubler in the modern day, and while the ability to turn that mana into power is nice, the lack of evasion really hurts this cards ability to serve as a reliable finisher, even with an Urborg, Tomb of Yawgmoth in play
Even older players should keep these MTG codes in mind too, as new ones get added every few months - and it's always worth taking free stuff when it's available
Locations and elements like chocobos, moogles, and summons (like Bahamut, Shiva, Leviathan) are included, letting players relive classic moments
