Marina Vendrell | Mirror Room // Fractured Realm | Opalescence

(and one other card)

Activate Marina by tapping it, unlocking
Mirror Room.
Mirror Room triggers twice.
Resolve the first trigger, creating a token copy of Marina.
Put the tapped Marina into your graveyard due to the legend rule.
When the Marina token enters the battlefield, it's first ability triggers twice, causing you to look at the top seven cards of your library and put all enchantment cards from among them into your hand and the rest on the bottom of your library, and then repeat this once.
Resolve the second
Mirror Room trigger, creating a token copy of itself, as it is a creature due to
Opalescence.
Activate the Marina token by tapping it, unlocking the token
Mirror Room.
Repeat from step 2.
