What it does
I don't have reliable information about a Magic: The Gathering keyword or ability called "Ruinous Ascension." This doesn't match any official MTG keyword, ability word, or mechanic that I can confirm.
It's possible you're thinking of:
- Ascend — a keyword granting "the city's blessing" (and Monarch-style bonuses) once you control ten or more permanents, enabling effects on certain spells/permanents.
- A specific card name rather than a keyword (many cards use flavorful titles).
If "Ruinous Ascension" is a custom card, a card from your playgroup's homebrew, or a Mythicwyrm-specific creation, I'd need the actual rules text to explain it accurately. Could you paste the card's text or clarify whether it's an official card? I'd rather give you correct rulings than guess and mislead you on something that matters during a game.
