Good to know, and you are very welcome! As for Nightmare Wheel, according to Nightmare Wheel (Duel Links) - Yugipedia - Yu-Gi-Oh! wiki , players can’t get it, yet. Duel Links cards released from the Shining Hope Main Box (?) and beyond-- as well as Lava Golem, even if only retroactively-- inflict half as much effect damage as they would in real life. I hope this explains things!
