So Im not going to spend time rehashing a Dinosaur tribal list here

While Cazur provides a great source of counters for the unblockable Ukkima, Ukkimas second ability implies that you want to sacrifice or bounce/blink it for full value
It helps show off a love for a specific card or character, and great custom ones can go even further than that
but just know that there is a chance it could fail (I still have a stack of Summoning Traps laying around, and it's slightly depressing)
Especially in Sealed at the prerelease, if your pool includes enough fixing, dont hesitate to explore such a deck or even splash a fourth color
