This guide will make (i hope most) of meepo games as fascinating experience as possible. It doesnt show to play like a BOSS, but it might teach you some usefull stuff. First off all, set up your group binds.
If you dont want to have too complex group binds, you can stick with.

(simple group bind)
1 - Main meepo
2 - All clones

(complex group bind)
1 - Main meepo
2 - All clones
3 - 3rd meepo
4 - 4th meepo
5 - 5th meepo
*6 - 2nd meepo (*This one is not neecessary at all).
