Yu

{u}{u}{u}{w/u}
Yu: Master of Water and Fish. If you can decipher its true name twice, sacrifice 10 symbols, and pick 5 numbers while using an RNG between 1 and 20, you will achieve this mythic card. It allows you to either control a Grand Flood, temporarily access the Fountain of Youth, or summon a Legendary Fish of your choice (reference rules for more detail). You may also keep this card as a relic and more (reference
rules).
