Dude, seriously, the grammar needs work...
You wouldn't really need Shaymin lvX that much or even that often anyway. Once you get Tangrowth lvX active with an Expert Belt it will have 170 HP and with the help of its power and Moo Moo Milk with 2 or 3 Junk Arm to reuse them Tangrowth should have enough HP to be doing Swallow for 140 damage. Metapod is one of those meta specific techs. you would only use it if you know that you're bound to face at least 2 {R} decks but the most common {R} pokmeon nowdays is Blaziken FB lvX which can one-shot and outspeed Tangrowth decks so that one is pretty much an auto loss so there's little you can do about that, just playing Metapod and Shaymin lvX gives Blaziken more to drag up and the most common partners for Blaziken FB lvX is Luxray GL lvX and Garchomp C lvX so your bench supporter will get dragged forward and/or sniped.
Just stick with Shaymin lvX (1-1) and Sunflora HGSS. Those are your best options.
