How do you get fish on jumpstart?

You can't get fish on Jumpstart. Jumpstart is a Magic: The Gathering format that focuses on using pre-constructed 20-card packs called Jumpstart boosters. These boosters are designed to be played immediately and don't include any cards that specifically represent fish.

It's possible you're thinking of another game or card format.

If you could tell me more about what you're looking for, I might be able to give you a better answer. For example, are you looking for:

* Fish in a specific Magic: The Gathering set?

* A Magic: The Gathering deck archetype that uses fish-related cards?

* A different game that features fish?

Let me know and I'll do my best to help! 😊
