Yeah I saw an opponent doing the same thing, with Birgi, God of storytelling, they were able to generate infinte mana, rather than a loop of casting ignus without generating mana (it cost 4 mana and produces 4 mana). On the snapshot, they began the tour with Birgi on board and 5 mountain, then cast ignus and begin to generate infinite mana. I joined the logs if needed.
