Hey guys, been playing this for a while, if you liked the first one you’ll like this one. I just found out about it a week or so ago, might want to give it a try. 
Are you playing a translated copy of it with an emulator? I didn’t think it was released outside of Japan. Loved the first one!
Yeah I loved the first one! Imakuni was such a funny guy. I had every card except for the two that you could only get through Mystery Gift or something. Only problem was I was the only person who played that game at my school. 
I’d definitely love to give PTCG2 a shot if there’s a translated version out there.
There have been some people dedicating their time to the translation of the game, with this IPS you can patch the Japanese ROM and play it on the Gameboy Emulators:

ROM:

Use this patcher on both the IPS file and the ROM (make sure to unzip the ROM before patching):

Once the ROM is patched you can open it with the Emulator, I use Visual Boy Advance to play it.
Enjoy!
Edit: How silly of me, here’s the patched GBC file so you can avoid all of the above and start playing:
