What it does
"Blizzara" isn't a real Magic: The Gathering keyword or ability—it doesn't appear on any official card or in the comprehensive rules. It sounds like it's borrowed from the Final Fantasy series, where Blizzara is a mid-tier ice spell.
That said, Magic recently released a Final Fantasy Universes Beyond set, so it's worth checking the actual card name and its printed rules text rather than assuming mechanics from the video games. If you've seen "Blizzara" on a card, it's likely flavor naming attached to standard Magic keywords (like a damage-dealing instant or sorcery), and the real rules will be whatever's printed in the text box.
If you can share the exact card or its full Oracle text, I'll happily break down what it does, the common rules pitfalls, and how it plays in Commander.
