Need help with metal deck

[SwampTide]

Hello, I'm kinda new to pokémon. I already made a deck, so here is:

Metagross :setsLA: x2
Metang 65 :setsLA: x4
Beldum 83 :setsLA: x4
Jirachi :setsRR: x1
Bastiodon :setsPT: x2 :setsOP6: x1
Shieldon :setsPT: x3
Armor fossil x3
Switch x3
Leftovers x2
Night Maintenance x2
Poké Radar x3
Life Herb x4
Technical Machine TS-1 x4
Underground Expedition x3
Looker's Investigation x1
Cynthia's Feelings x1
Bebe's Search x2
:metal: Energy x9
Special :metal: Energy x4
Upper Energy x2

The strategy is: Use the evoluters to reach Metagross, and have it in the field the longer for hit with 100 dmg. When Metagross has enough damage, use Switch and change it with Bastiodon, heal Metagross in the bench with Life Herb, bring it back when is healed.

So, I guess that need another 2 Metagross, besides that, Any suggestions? Do I need mix it with another type or change it totally? Any tips are welcome, thanks.

This is pretty good for a beginning decklist. You should try to add a 2-2 claydol and 1 uxie la.

warp point is generally better than switch
as it also forces your opponent to switch when they may not want to

You can also control what they switch with metagross!

-3 Bastiodon (Not great)
-3 Sheildon (Now not needed)
-3 Armor fossil (Now not needed)
-2 Metang (Use some rare candy, so you don't need 4)
-3 Switch (Warp point is better)
-2 Upper energy (Double colourless energy is better)
-2 :metal: energy (You have plenty)

+1 Metagross LA (More attackers)
+1 Metagross SV (Lowers HP for easier KOs)
+1 Nidoqueen RR (Heals you inbetween Every turn)
+1 Nidoran (Female) (Evolves into^)
+4 Rare candy (Skip the stage 1)
+3 Warp point (Better than switch as spidy said)
+2 Claydol GE (Draws cards)
+2 Baltoy GE (Evolves into^)
+1 Uxie LA (Draws cards)
+2 DCE (Better than Upper)
