It's the umbrella frill that does it for me. It'd look so much better if it was just a mane, or not even there at all.
Edit: Calling it now. Entei's form is going to be some sort of horrifying triceratops, pterodactyl, or hadrosaurid (duck-billed) abomination.
I saw someone go through the past Paradox 'mons on Pokébeach when they revealed Raging Bolt and Iron Crown and they mentioned that none of the saurian body plans were reused, that kind nixes the possibility of a pterosaur-themed Paradox Entei.
Would it be worth it to get a booster box or at least a trainer box of a current TCG set? I like Giratina and intend to keep any cards I get.
Maybe in the near future there will be an Eon Pokemon themed set so I've been holding off.
That depends on which set you want to get and why you want to get ‘em. The SWSH-era sets are terrible when it comes to pull rates for a few reasons (Secret Rares/Alternate Arts aren’t guaranteed in a box, some boxes are expensive due to them being out-of-print) but are good resale-wise. Here’s an example of one of the more recent SWSH-era sets.
A word of note here: the Trainer Gallery cards are basically Alternate Arts prints of older cards (The Pikachu V/VMAX combo here is technically from Vivid Voltage, a good 7+ sets behind the one listed here) that feature a Pokémon and a key human character associated with ‘em. Another thing is that they‘ll replace the reverse-holo in a pack Rather than being in the rare slot.
The SV-era sets are pretty damned good pull rate-wise (Alternate arts and Secret Rares take up one of the reverse-holo slots rather than being in the rare slot) but are terrible when it comes to resale.
And yes you’re seeing this right, the only expensive card is the Secret Illustration Rare Iono. The Magikarp is an outlier since it’s supposedly really hard to pull.
And for reference, these are the most expensive Charizard cards printed in between Sun & Moon and Crown Zenith on the top and the most recent set featuring Charizard (they on presale now but the prices will more than likely drop as more cards are pulled).
There’s another set where Charizard is featured coming out in September but that one has a delayed drop.
