[Gen IV] Help with HG Team (in-game and competitive)

[Skuntank]

Currently I am planning on using these pokemon in my next run of HeartGold. I am going to trade them into the game in the beginning so i can use them in it's entirety I just need help with movesets and if you can add suggestions it would be very helpful. I wouldn't mind changing some pokemon around also...
(note: i am only using gen 1-2 pokemon and their evolutions for the sake of nostalgia)

1.Meganium
-Sythesis
-Reflect
-Magical Leaf
-Poison Powder

First of all, you're supposed to have all 6 Pokemon with movesets before we can rate and such. Secondly this should be in the In-Game team forum because no way is this competitive. o_o
