Ok so, all day for the past two days, in Omega Ruby, I went GTS hunting for a shiny Rayquaza. People asked for the weirdest things offering their shiny Rayquaza like Barbaracle, Meowth, Magcargo, Milotic, and even Trevenant, (all level 91 and above). Me, I'm over here searching for some of these Pokemon and usually some of them offer those Pokemon for a Pokemon too risky to trade. Earlier today, I saw a trainer offering a shiny Rayquaza for a Trevenant that was level 91 or above. I look at it at a few minutes wondering if I could get one quickly enough from searching Trevenant on the GTS. After looking, I went back to the Rayquaza section and the Trevenant request was still there (and was for about another 5-7 minutes). I felt safe, I searched up the Trevenants again and one guy offered a level 100 Trevenant for an Arceus. I traded my only level 100 Arceus for that Trevenant at the time so that I could quickly go back and get the shiny Rayquaza. By the time I got back to the Rayquaza section, the Trevenant request was gone... I was disappointed for a few minutes and felt a bit salty but then quickly moved on, because the Arceus didn't really matter that much. Afterwards, some guy asked for a Moltres offering one, I went looking for Moltres in gts and they were asking for Manaphy (See Other Information). I was like nope, not making another risky trade like I did with Trevenant... I went back to the Rayquaza section and that request for Moltres was already gone, so I was lucky. So I'm over here for another hour or two still searching up shiny Rayquaza and even Wonder Trading and then I find a regular Rayquaza user requesting a Deoxys. I'm like wynaut because they said please and I had 2 Deoxys anyway (Also after all of this, I deposited that regular Rayquaza for a Kyogre and it worked). I traded the Deoxys for a regular level 76 Rayquaza, and a few minutes later, I think I saw the same guy offering a level 100 Rayquaza for another Deoxys... Ok so afterwards I find a shiny Rayquaza user offering a Deoxys, I didn't hesitate, I went lightning speed towards my last Deoxys and traded it. I finally got a shiny Rayquaza!
Other information:
Some time when I was randomly Wonder Trading in the process of trying to get a shiny Rayquaza in the GTS, I got a shiny Manaphy which I didn't realize that it was shiny at first (because they barely look any different). I decided to keep it just in case anyone requested a Manaphy for a shiny Rayquaza. After I finally got the Shiny Rayquaza, I deposited the shiny Manaphy in the GTS for an Arceus and I asked specifically for the Arceus not to be shiny. Soon after, I got a shiny Arceus. I rather just found that funny and went back to the GTS knowing that Arceus users would send their Arceus just to ask for another Arceus. Soon after, I found a regular Arceus and traded my shiny Arceus for it. I find out the the Arceus I got was far better than the one I traded for Trevenant in nature, IVs maybe, and it even had ribbons/pokeblock training for the Pokemon Contests.
Basically what I'm saying here is that my day turned from facepalm worthy moments, to ode of joy.
