IS Nocturne OTK

Your goal is to use Oblivious Islander five or six times on a Zephyr Sage to then make it cost 0 or 1. This then can be used with Nocturne to reduce the attack of enemy units until they can't block your army, leading to an easy attack.

You can tech in handbuffs to ensure you get to win, but tbh Noc and 5 Sages are pretty much enough to win, because 6 + 5x4 = 26. So they would need to somehow have ways to make two units have at least 3 attack, and that is if they have more than 18 Health.
