Lol, depends on which colour the game is,
Grouvyle will learn leaf blade at lvl 29.
grovile learns leaf blade 28 or 27
Well,you'll have to defeat the e4 with Rayquaza.For the champion us Leaf storm/blade on Wailord then earthqauke on Tentacruel(even if it's water type,it still works.On Milotic,leaf storm/blade.I think leaf storm on Ludicolo not leaf blade(the higher the level,the more power).Leaf storm/blade on whiscash and finally leaf storm on Gyrados not leaf blade.
Sceptile's leaf blade
Unfortunately, shiftry does not learn leaf blade. It does however learn leaf storm at level 49 (power 140 accuracy 90) which does amazing damage. I hope this helps
A blade is the expanded part of the leaf
Solar beam. (grovyle learns leaf blade and it is like razor leaf)
you find it somewhere out side stark mountain but i cant remember where
there is no TM at all that contains leaf blade
Astonish, Absorb, Growl, Razor Leaf, Leaf Blade, and Leaf Storm is all I know but there is lots more movess that Lotad can learn.
The function of the leaf blade is to abosorb light and make food.
Sceptile learns leaf blade at level 22.
