If you want to try out a companion but want to keep the deck building easy I suggest picking up the Painbow precon from Dominaria United
Unfortunately I havent been able to find any way to get them in the UK
As for Japan-resident kids under 15 purchasing items from the Pokmon Center Online, that would require a credit card, something they cant get either, so they were already going to need their parents help making the transaction, so a parents My Number can be used for their order
That hypothetically means you could reach the 20 lore needed to win in just four turns once the cards power kicks in - making it a powerhouse card, and one of Lorcanas best cards when it comes to decks built around churning lore as quickly as possible
The combination of cant be countered and ward 4 here makes the Dinosaur tough to deal with either on or off the board, while its trample, haste, and high stats make it imperative that your opponent does deal with it
This can be pretty doable between free packs, the Wonder Pick function, and Pack Points
