Immortus, Maestro dell’Eternità

: Add for each card you've drawn this turn. Spend this mana only to cast noncreature spells.

Power−up — : 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.)
