What it does
"Blade of Magnus" isn't a standard Magic keyword or ability—it's actually the name of a specific legendary equipment, Sword of Body and Mind isn't it either. The card you're likely thinking of is Goblin Goon or, more accurately, the term doesn't correspond to any official MTG mechanic or card.
If you meant a specific card or homebrew effect, double-check the exact name. Equipment cards on Mythicwyrm often borrow flavorful titles, but there's no published Magic ability called "Blade of Magnus." It may be a custom or unofficial card from a community set.
For accurate Commander advice, share the card's full text. I can then break down how its abilities work, common rules pitfalls (like equip timing or triggered abilities), and its value in a multiplayer EDH game.
