What it does
I don't have reliable information about a Magic: The Gathering keyword or ability called "Phaeron." This isn't a standard MTG keyword that I can confirm exists, and I don't want to invent rules text or mechanics that could mislead you during a game.
It's possible this is a card name, a typo, a very recent mechanic I'm not familiar with, or something from an unofficial/custom set rather than an official keyword. If you can share the exact card or set it appears on, I can help interpret it.
For accurate rulings, I'd recommend checking the card's Oracle text via Gatherer or Scryfall, or consulting the most recent Comprehensive Rules. If you meant a different keyword (the name resembles nothing standard), let me know and I'll gladly break it down for Commander play.
