Well Darkrai is a free space thankfully since its already been tested down here, Now we just need Lugia and Roaring moon and its the freest bingo ever. (Roaring Moon is the most broken thing in the tier right now besides Kyurem so I'm gonna go bold and say top row bingo is the most likely here to actually happen since Darkrai has already been tested, and Roaring Moon is very likely to be tested out of the tier.)
Anyway as much as the topic of testing Ubers down has been beaten to death already, I do hope the council considers the idea of letting Lugia be used in some OUPL tournaments like Darkrai was or at least give it a fair shake in OU once things settle down a bit, because Lugia's flaws of being exploitable by knock off/trick/status, as well as setup fodder against some physical sweepers like Kingambit and Trick Darkrai, could end up being exploitable enough to stay in OU, and Lugia could bring some decent defensive utility into the tier due to how fat it is. (Even if its Psychic/Flying type is a huge burden for it in that department, and well the bulk being obnoxious.)
Also fun to mention not that this necessarily gives merit to testing Lugia, but Lugia is just not good at all really in Ubers UU, a format in between OU and Ubers power levels as we all know, where even some stronger OU pokemon are viable or able to thrive. its not just outclassed by Necrozma Dawn Wings and Solgaleo as defensive pokemon, but its still too passive for the tier and not good on its own merits. Which is even worse than a pokemon like Reshiram, who is mainly bad up there because its just very outclassed by Chi Yu and Kyurem White, not that it couldn't be good necessarily without those two not being in the tier. Not that this is relevant but it just shows how weak Lugia is as a box legendary if its worse off than Reshiram and potentially gonna place even lower than the two Zamazentas and Reshiram on the Ubers UU vr.
