With the trainer box comes on guaranteed rare card which in this case was the charmander and then some dumb stuff like badges and dice for some reason

Just so you know in case you ever decide to open Sword and Shield elite trainer boxes, the included promo is a new thing they're doing for Scarlet and Violet era sets, and is not included with anything pre this year (Though, some special sets give you a promo in the past as well). Also, the dice and badges are for people who play the actual TCG competitively. ETB's are more geared towards people who play the game as are build and battle kits/stadiums.

9 booster packs which I believe include an extra holo compared to regular booster packs of this edition but please correct me if I'm wrong.

So, Scarlet and Violet era pokemon has changed MRSP prices, and to offset that balance you are guarenteed 3 "holo" cards in every single booster pack of Scarlet and Violet sets. So, you will get 2 reverses and 1 holo in every pack, doesn't matter which Scar & Vio set you're opening or what product it's from.

Also, ouch. This ETB was absolutely ass pull rate wise. I would definitely recommend buying a booster box in the future if you want to rip something as they are soft seeded with pulls in this new generation of the TCG. It's way more fun than ripping an ETB and getting barely anything, and honestly ETB's go for $40 on average which is almost half the price of a booster box (And, remember a booster box has 36 packs versus 9 with an ETB) on ebay or through an online LCS.
