How it works
Activate up to seven lands by tapping them, adding at least 2.
Activate Ashnod's Altar by sacrificing Great Whale, adding CC.
Fool's Demise's first and second abilities trigger.
Resolve the first Fool's Demise trigger, returning Great Whale from your graveyard to the battlefield.
When Great Whale enters the battlefield, it triggers, untapping up to seven lands.
Resolve the second Fool's Demise trigger, returning Fool's Demise to your hand from your graveyard.
Cast Fool's Demise by paying 4, targeting Great Whale.
Repeat.
If the seven lands can tap to produce at least 3, this combo nets infinite mana.
