Ok. Four players. T1 one guy did this
Swamp, {Dark ritual}, {Darksteel Ingot}, {Sol Ring}, {Felwar Stone}, {mana Vault}
Ok so about 10 turns in I had a possibility storm and an aggressive mining on the guy with the explosive start. My board looks a little like Zedruu, {Pucas Mischief}, and 9 lands. The rest of my stuff is scattered throughout the board. I play a mana barbs into an {Eidolon of the Rhetoric}. Everyone on the board just concedes
Lol crazy start!!
But lol nice combo finish :P
