gift ideas?

my friend has a birthday coming up and he’s SUPER into riftbound. he said recently he spent a lot of money on it but i have no clue what he has. i don’t know anything about it really (i may try to see if i can sneakily ask him to tell me about what he got)

i found a deck box that im going to 3d print and paint because i figure either he uses it or worst case is decoration or something lol

i’m assuming there’s packs of cards that are good to get? no clue which or how much they should cost vs scalper prices

any ideas would be great! leaning towards the less expensive side because i’m just trying to find a couple little things

thanks!
