Tangrowth!? (Emphasis on the growth)

I decided i wanted to make a different set to most Tangrowths. I found out that it learned Growth when i found a Tangela with it, and i decided to make a Tank that makes use of Growth to raise its Special Attack.

The Set:

Tumour@Leftovers
(252Hp, 252 Def, 6 Sp.A)
Relaxed Nature (-Speed, + Defense)
~Growth
~Synthesis
~Energy Ball
~Ancient Power

Ok so, what i plan to do with this set is to come in on a physical sweeper and start using Growth. I have synthesis so that i can recover off the damage i get while setting up. Energy Ball>Leaf Storm for STAB because of the Sp.A drop. The reason i have Ancient Power>Hp Fire is because with the evs it can survive a Brave Bird from a max attack Adamant Swellow, after Guts and proceed to OHKO it. Meaning it should be able to survive any flying attack that isn't special and OHKO if the pokemon using it is a flying type. So thats it any constructive criticism will be taken into account.

I like it though I think you should put some EV's into sp.def

relloz if you are going give advise back it up.

Dark, why Relaxed??? You aren't using Attack so Bold > Relaxed.

Because i already had a relaxed Tangela with 31/x/31/31/x/x

I suggest using focus blast over ancientpower (which is generally a terrible move unstab'd). Also try to fit sleep powder somewhere on this set; it's an awesome move
