If I'm reading the sell sheet correctly there are
18 parallels if you count the four PMGs:
- Canvas
- Leather
- Holofoil
- Clear Cut
- Lenticular
- Plexi
- Wood
- Metallurgy
- Blue Traxx
- Rainbow
- Seismic Gold – #’d to 92
- Orange Lava – #’d to 25
- Emerald Surge – #’d to 10
- Golden Treasures – #’d 1-of-1
- PMG Red – #’d to 100
- PMG Blue – #’d to 50
- PMG Green – #’d to 10
- PMG Gold – #’d 1-of-1
Plus the 100-card Variant Covers set (which itself is a sort of parallel set) that has its own numbered parallels. It's parallels within parallels.
