what was your proudest catch and why?

I felt proud after I caught my second Azelf with my last remaining three Pokeballs.

 

I think my Azelf, it got caught with my last Pokéball!

 

Probably my Roselia or Ralts. Caught both with just one ultra ball (each)!

 

Finally catching Azelf...after I lost 3.

 

Snorunt because I want Froslass and Glalie both!

 

Now, it's Entei. I had never seen a beast until then and it was a total surprise when I stumbled upon it. Caught it without much of an issue!
