Immortus, Master of Eternity [Marvel Super Heroes Commander]

Cost: 2 U U T : Add U for each card you've drawn this turn. Spend this mana only to cast noncreature spells.
Power-up — 5 U U : Each player shuffles their hand and graveyard into their library, then draws seven cards. Put a 1/ 1 counter on Immortus. (Activate each power-up ability only once. Reduce the cost by his mana cost if he entered this turn.)
