Activate Ghired by tapping it, creating a copy of the Fear of Missing Out token.
When the Fear of Missing Out token enters the battlefield, it triggers, causing you to rummage.
Move to your combat phase and declare the Fear of Missing Out token as an attacker.
The Fear of Missing Out token triggers, untapping Ghired and causing you to get an additional combat phase after this one.
Repeat from step 2.
This cunning loop harnesses the synergy between token creation and extra combat phases to generate endless value. With Kratos, God of War granting all your creatures haste from the very start, you are free to immediately tap Ghired, Mirror of the Wilds to copy an existing token of Fear of Missing Out. Each time that token copy enters the battlefield, its triggered ability lets you discard and draw a card, fueling your graveyard while churning out a horde of tapped creature tokens. When you move to combat, the Fear of Missing Out token attacks to trigger delirium—assuming you have four or more card types in your graveyard—which untaps Ghired and grants you an additional combat phase, allowing you to repeat the entire cycle anew.
