What keeps Hoopa-U from being one of the most used competitive Pokemon?

Hoopa-U seems to be a totally overpowered abomination. 680 BST, offensive stats nearly rivaling that of Mega-Rayquaza. A solid choice of moves, access to boosting moves too. Low speed to take advantage of Trick-Room. Access to a handful of high base power moves. Magician isn’t a bad ability either, and it only has one weakness, to a lesser-used type.

I get that Hoopa-U is in Ubers (I think) but at this point it feels like something everyone would want on every team.

To quote’s Hoopa-U’s Gen 6 and Gen 7 Smogon analyses, the reason is this:Gen 6 Ubers analysis

Despite that, however, its viability should not be overestimated, asstall is the least solid playstyle in Ubers and Hoopa-U is vulnerableto all forms of status and entry hazards. In addition, Hoopa-U ishindered by its mediocre Speed and pathetic Defense, which leaves itsusceptible to physical attackers and priority moves.

Gen 7 OU analysis

On the flipside, its middling Speed stat, despite being good for awallbreaker of its caliber, leaves it at the mercy of a number offaster offensive threats in the metagame such as Mega Medicham,Kartana, and Tapu Lele. It also carries poor physical bulk along witha 4x weakness to one of the strongest momentum-gaining moves in thegame, U-turn, meaning that Hoopa-U tends to get overwhelmed by thelikes of U-turn Tornadus-T, Greninja, and Tapu Koko.

In short, the reasons are as follows:1. 4x weakness to U-Turn is a severe downside, means it gets revenge killed by a lot of offensive threats.2. Mediocre speed and pathetic defense means it easily gets revenge killed by faster offensive threats.3. In the case of Gen 6 Ubers, stall-breakers not being in very high demand.Source:https://www.smogon.com/dex/xy/pokemon/hoopa-unbound/https://www.smogon.com/dex/sm/pokemon/hoopa-unbound/
