Different Pokmon eras and card types use different holographic technologies
We suggest this may be due to the foil commons being syphoned off to fill the 9 foil common/uncommon slots in the Collector Boosters

I like the dinosaur more, as it is a threat on its own, so you can bring it in against decks like Niv-to-Light (for Omnath, Locus of Creation) and Black-Red Midrange (for Graveyard Trespasser and Kalitas, Traitor of Ghet)
These decks can be vulnerable to board wipes, so putting all your creatures beneath Abdel protects you
To tell if your Pokmon cards are rare, check for special features like 1st edition stamps, holofoil designs, or limited prints
