I thought my battle with the magikarp was good stuff, but I most pleased with this battle as well. As for strats Whopper should eat the ember attacks and just block magby and force Hops to guard it while Aron and Nincada double team the bird. If Natu can avoid both of them attacking then we triangle magby and take it down, ignoring the other two as it can't get three attacks blocked and take them down 1 by 1 starting with that. If Magby goes for the one on one with Aron, I think mudslap super-effective stab plus accuracy down should take the cake. Acutally might be better to start with that as it has a higher chance of working.
