Your opponent faces you from across the table, unaware of how completely they are about to be obliterated.
You smile knowingly at them as you drop the first Black Lotus along with your land of choice. Maybe you could imprint Time Walk onto Isochron Scepter and tap it immediately, denying your enemy the chance to play even a single measly turn. Perhaps you'll wait, giving them false hope for a turn before a Panoptic Mirror enters the field. Or, you could baffle them momentarily as you play an Amulet of Vigor and an Esperzoa before slowly laying down a Time Vault.
Whichever option you take, the opposing player's face will surely fall, as they suddenly realize that there will be no more turns for them.
They can only wait, shaking, terrified of what is to come.
And what will you do with all these turns, you ask?
Wait until you can hard cast Emrakul, the Aeons Torn?
Pfft.
Progenitus?
Hell no!
A vastly complicated combo involving 15 and a half cards that ensures the destruction of the world as we know it???
Get out of here!
You, my friend, will play a single Storm Crow
The other player will laugh at you, slap their sides and make crude remarks about your mother."That's what you wasted infinite turns on?!" they will cry, "a Storm Crow?!" But that laughter will cease as you play Progenitor Mimic, changing a single bird into a living storm of crows.
As they watch the flock grow, they see a glimmer of hope through the clouds of feathers.You can't keep having turns forever, eventually you'll mill yourself out!
Until you play Platinum Angel, crushing the last of their hopes, dreams and aspirations as they are faced with the horrifying fact that they cannot possibly win.
They can only watch in horror as they are deafened by the sound of infinite wings beating the air, and crushed by an endless deluge of crows.
You leave the table victorious, it was $35,000 well spent.
