Need Tyranitarite!

I have pokemon Y, and the Tyranitarite is an exclusive to X as most of you probably know. I'm willing to trade pretty much anything for it. Here are the things I have up to trade for it:

-Any of the regis
-Ho-oh
-Aggronite
-Kyurem, Zekrom, Reshiram
-Mewtwo
-Terrakion, Virizion, Cobalion
-Latios, Latias
-Heatran
-Palkia
-Zapdos
-Cresselia
-Mesprit, Uxie, Azelf
-Shiny Haxorus or Dragonite
-Pinsir + Pinsirite
-Lv. 1 squirtle with dragon pulse + aura sphere

I want dat squirtle.

Really though. I have no idea WHERE you catch Tyranitarites. And I'm not really a pokemon fan (though I did play the games).

I have 3 Tyranitarites. You could just have one for free. And also, Squirtle with Dragon Pulse is redundant. You could just run Ice Beam and also hit Flying and Grass types SE.
