Free Giratina-Altered (the one without Levitate), for comparison, Ting-Lu is just a better mon
Ting-Lu has:
-Better typing, not being weak to Dark and Ghost while also providing an Electric immunity.
-Better bulk thanks to its ability
-Can actually do a lot with said bulk (set SR/Spikes, force chip damage with Ruination, phaze threats) unlike Giratina who can at best click Dragon Tail in front of a +2 Dragonite and miss
-Isn't Gambit/Roaring Moon/Darkrai food
Meanwhile Giratina can't even pivot like Pecharunt, another bulky Ghost that not only is almost as physically bulky as it is, but also has reliable recovery and doesn't autolose to Toxic like Giratina does.
And we only really get positives with Giratina in the tier, like another Waterpon/Zamazenta/Iron Moth check and a Defogger that can kinda do something to Gholdengo, all in one, and the lack of reliable recovery prevents it from being anything insane, honestly, Dondozo is even more broken than this
It also kinda beats Palafin, so you have even higher chances of finally unbanning this guy like so many people want.
