You'd need an Armor Fossil for those, though... and you'd then wanna have a playset (4) of Fossil Excavator in order to get those out. And this is essentially another Stage 2 line, which would bog the deck down. And Bastiodon is not a very good heavy hitter, especially for a Stage 2. Plus, you mistyped Bastiodon's PokeBody, which I added what you were missing in bold and underlining.
