Right so in all the years I've played Pokemon, not ONCE have I ever used an X-Anything, perhaps if I have a spare turn in battle against a poisoned opponent but I don't know when and where these things are actually useful. Who's used them? What for? ~ Just curious
The only time I've seen them used is for low level runs or solo runs, where the player's pokemon are far too weak to fight but can survive a few turns to spam x-attack, x-speed and x-defend and then heal up.
I've seen people use them in Nuzlocke runs. You really need to be cautious in those, so it makes sense to set up some extra attack or defense while you have the chance. Personally, I sell mine the moment I get them and buy a few balls with the money instead.
The only time i've ever used them has been for gym battles. I've never touched one Post-E4 though
Haha! Funnily enough, I'm playing emerald right now and Brawly's Makuhita likes to Bulk Up a lot. So after 2 losses in a row I decided to use X-Attack and X-Defend... I won!! So these X-items really can help you!
Played since Pokemon Red and never have I ever used one! I feel why use it when you could just do more damage with the extra turns. For example if I use an X attack on my treecko and used Pound and it did 13 damage, I could do more (about 20) if I did 2 hits and take less damage.
I've never found a need to use one. I don't remember if I tried it once back in the day, since I didn't really know what they were used for. I would see Gym Leaders do this a lot in Yellow, more specifically Giovanni and his Guard Spec., but I've been seeing this less and less. I actually gave my DS a weird look when I think an Ace trainer, if not one of the sports people in the Big Stadium/Small Court, used an X Attack in Black 2.
So I don't think I'll ever use one, even though people here are saying they're great for Nuzlockes--which I may never do myself, but that's something else entirely.
