5 Explorer's Guidance is a Risky Consistency Booster Released in SV05: "Temporal Forces" Discarding cards is not something that many decks in the Pokmon Trading Card Game want to do regularly, but the few decks that do make it a part of their core gameplay
Any help appreciated thanks Re: the Holon Phantoms pack curve doesnt indicate anything because theres a reverse holo in each pack, and they have similar curvature as holos
Their effects generally apply after destroying a monster, and help them destroy monsters more easily, but many of their effects also deal with Normal Monsters or give an advantage during battle, like "Exarion Universe" and "Enraged Battle Ox"
The Legendary Fisherman and Buster Blader are two other well-known ultra rares
Keep a lookout for these troublemakers
TEN-001 Nightmare Moon, the Immortal Shadow She's a nomi monster (oh no!), but can be chocked to the field easily with cards like Allure of Darkness (after the time lag - which awesomely will start causing your opponent to panic.) (Protip: she self protects against Bottomless Trap Holes hahaha) She automatically gives you +1 by tagging along with the Eternal Night Field Spell, as well as protecting it from S/T destruction, and causes opposing monsters to "bow down" to her
