Tyranitar

The rise of Latios and Latias has given Tyranitar a boost in viability in the Ubers tier, as its ability to Pursuit trap them is invaluable on some teams. Tyranitar also shines in a Flying- and Dark-type dominated metagame, taking on the likes of Arceus-Dark, Darkrai, Ho-Oh, and most offensive Yveltal. Sand Stream is still a very good ability despite Primordial Sea and Desolate Land dominating the tier. It greatly increases Tyranitar's Special Defense, wears down foes with passive damage, and supports Sand Rush Excadrill when harsh sunlight and heavy rain aren't active. On the downside, Tyranitar is complete bait to Primal Groudon and Primal Kyogre; both have the type advantage, and their weather-activating abilities override sandstorm. Tyranitar is also quite slow, so it will nearly always take a hit before it does anything. Most importantly, its mediocre defensive typing and lack of reliable recovery make it somewhat easy to wear down, limiting its capabilities as a tank. Nonetheless, Tyranitar shines in a metagame infested with Latios, Latias, Flying-types, and Dark-types, so it is worthy of a spot on many teams, from offense to full stall.
