Training Help?

I recently traded my awfully named draik day draik (draikity33333) for a grey grundo named K0, and I figured with a name like that I simply have to make him a BD pet :P I was wondering, what are the quickest or cheapest ways to train him? I'm thinking of zapping him once he reaches level 50 (I heard this is when the lab ray will stop making him go back down to level 1) is this wise? I'm a complete noob in the BD :P Thanks :)

what I've been told is that if you're going to get him as a challenger that day it'll be on your first winter random event. so refresh until you get a winter RE and then move on and try again the next day. I'm still waiting to get Shadow Usul :(

[center] Hmm, in that case, I'm done for the day. I got hit with a snowball or some such thing... But on a side note, I didn't know your pet could increase in intelligence from cliffhanger... "DarkendSpirit says "Wow! I learned so much!!!" DarkendSpirit's intelligence level has increased. You win!!!" ------------------------------------------------------------------- [url=http://www.neopets.com/browseshop.phtml?owner=raine_storme&misc]~~ Come visit my map shop ~~[/url] [/center]
