Help on Tangrowth/Seperior deck

[RevYolution]

I feel that I should mention that I am a player that is trying to get back into the competitive scene after ten years or so. I have had success with tangala and tangrowth from cl and would like to add in seperior from blw into a deck. The theory of having these two as the mains is that with enough energies on tangrowth it is a real heavy hitter with the potential for OHKO on most opponents. This leads the need for energies so I know energy search and others like are needed. seperior i wanted because it can heal any grass and deals good damage for two energies with no retreat cost.

Now I know this is a very general post but any suggestions on where I should focus to really make this deck idea bloom would be awesome.

Thanks
