Depends on the remaining cards. Most of the ultra rares aren't really good and the only good super rares are Ceruli, Jain, Ghosts from the Past and maybe the Gem-Knight fusion monsters.
Personally, I plan on resetting after getting Snoww, Volcanic Rocket, DW Lightning, and maybe Lyla. DW and Volcanic can definitely be relevant currently, but I doubt Lightsworns will have the same luck until we get better boss monsters.
