Quest Through Time

When this enchantment enters, draw a card and note the name of three legendary noncreature artifacts with different names. Whenever a permanent with one of the noted names enters under your control, scry 5. Then, if you control all permanents with noted names, exile this enchantment and each player shuffles their hand and graveyard into their library, then draws seven cards. You, then, create a 1/1 colorless Hero creature token and put two +1/+1 counters and a lifelink counter on target creature you control.
