Quite a decent all around Pokemon. I've been keeping an eye on Tsareena for awhile, and I have to say, it has the tools to work in UU, with niches in OU. 72/98/98 bulk is quite workable, and access to Rapid Spin means that it can remove hazards decently. 120 attack is respectable. Not eye-poppingly crazy, but it could make for some moderate wallbreaking. 72 speed is a bit of a dead zone, as you're not fast enough to deal with Pokemon above that, but not overly slow to work in Trick Room, either. Quite average in many respects, but a Jolly nature and/or a Choice Scarf can mitigate this somewhat. In terms of movepool, it's fairly shallow, but it has the moves to fill certain roles. With Rapid Spin, Tsareena can fulfill the role of a bulky spinner. With U-turn, you can keep the momentum going, VoltTurn core or not, and/or pivot out of danger when needed. With High Jump Kick, you're not walled by Steel-types, though it comes at a heavy cost if you miss. Trop Kick, which is the sole signature move of this butt kicking fruit queen, you can threaten physical attackers. Heck, there's still plenty to work with, like Synthesis to keep you healthy, Play Rough for coverage against other common types like Dark and Dragon, Acrobatics to snuff out Pokes like Heracross and Breloom -- The tools you have at your disposal, while minimal, are quite useful for utility and moderate wallbreaking.
While the main focus of Tsareena is to snuff out priority attacks, it can possibly serve some key roles to a extent. Grass, especially pure, is a tough type to work with, but Tsareena has great potential.
Might be overselling it here...
