Or you can actually Baton Pass the Tail Glow of course ;). And maybe Substitute too.
-Tail Glow
-Baton Pass
-Thunderbolt
-Substitute/Ice Punch/Water Pulse/Silver Wind
Last slot depends on what you want. if you take Silver Wind, you get your original set, which has the best coverage, but Silver Wind does not get a boost from Tail Glow. But it's epic to Baton Pass a lucky Silver Wind boost. Substitute is another nice move you can Baton Pass. As for Ice Punch or Water Pulse, Ice Punch is better, but from emerald move tutor, Water Pulse gives coverage against Ground types as well, but leaves you impossible to break Grass types. Do not use Signal Beam though, it's not worth it with Tail Glow, nor Baton Pass, while Silver Wind could give you that lucky stat boost.
