I know it sounds stupid but if you have caught a Hoothoot and raised it to Lv. 10 AND called it BIG PEA a glitch makes Bugsy start using slightly easier attacks on you.

To get Entei Suicoone and Raikou you go to the Burned/Burning/Burnt Tower and go up to where the things that look like Rattatas in your party (I know Silver and Gold don't have the best quality in the world but I like to exaggerate) are and as soon as you go to the one nearest the bottom of the screen (Raikou)
they all run off. Go back out of Burnt Tower using the ESCAPE ROPE and go to the biggest patch of grass near by. Use TM Sweet Scent and Raikou appears, then Suicoone, then Entei at Lv. 70 or 50 or 5 depending on how strong you are.
