#623永劫の支配者、イモータス

{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.)
