I'm not sure if this is the right place to post, so if it really is please shift it to the right one.
I'm looking to teach my Tyranitar 2 moves, a.k.a. Pursuit and Stealth Rock. Pursuit is learnable by a few Pokemon, and Stealth Rock can be obtained by transferring a Pokemon from D/P/Pt to the Gen V versions. However, there are no 2 Pokemon that can learn both moves. How can I make Tyranitar learn both moves?
