Careful though on the Mechanical Scorpid, the Murloc Harbor strat requires the breed 5 (aka S/S) version and there are 5 different breeds IIRC. I got the breeds 4x1, 7x2, and 11x2 IIRC out of the 5 I built
Ended up having a great guildmate who doesn't pet battle sell me a 5 for 1k, and for the record it was after I told him why and what it was worth. And to top it all off it was the first scorpid he built... some guys have all the luck. I sold a 7 and and an 11 for 850g each and gave the others away to guildmates who are getting into pet battling just so they have them.
