As I mentioned before, the most powerful way to build Commander decks with MDFCs is to cut five or six lands (usually basic lands or other utility lands that tap for one color of mana) along with two or three spells and replace them with MDFCs so that you end up with something like 31 or 32 "real" lands but 40 or 41 total lands
I love a land that does something when I draw it on turn 7
The problem was, this card got overshadowed by some of Standard's bigger issues better cards at the time: Felidar Guardian, Aetherworks Marvel, and Gideon, Ally of Zendikar
Fast Mana Fast mana is one of the most common ways to end a game of cEDH, even if it isnt directly the thing that wins
Good players are going to undervalue this
Good luck experimenting with your new proxies, and have fun playing Magic with friends.
