(Jace 2's 3rd loyalty ability). Moon prison the scion netting you minimum of 3 mana, 15 or more if you had it buffed via unravel. Now every time you draw a card it buffs moon prison by 4/4 which can result in you gaining absurd amounts of mana each turn. Just make sure you have the card draw to support such crazy mana gains. Games usually end quite quickly at this point.
