What it does
I don't have reliable information about a keyword or ability called "Ultima Founding" in Magic: The Gathering. This doesn't correspond to any official MTG keyword or mechanic that I'm aware of.
It's possible this is a misremembered name, a card-specific ability, or content from a custom/unofficial set (like a Mythicwyrm-specific creation). If you can share the exact card text or the card it appears on, I can explain how it actually works, including any rules nuances and Commander relevance.
If you meant a different mechanic—such as "Foretell," "Forecast," "Cumulative Upkeep," or something from a Final Fantasy-themed set—let me know and I'll give you an accurate breakdown.
