What are some ponies you cannot believe they gave us for (essentially) free?

Like ponies that you find so pretty you'd think the only way you could interact with them was to stare longingly at them in the shop because they'd make you buy it for hundreds of gems or actual money, but they gave it away for nearly free (less than hundred gems in shops, hotels, community events, seiges, blitz, etc.)

For me, I'd say imperial discord (I could not believe he is a prize fr he feels like he costs a 1000 gems),

future diamond tiara (!!! She's so cutee???),

the kirin in hotels/community/ad pony streak they had,

the creepy shadow guys (wizened nightmare, feline nightmare) everyone hates on lmao 😭

the characters in the robotics+ edgy+ raindeer seige events they had,

Open friendship student (I find her so pretty), dream berryshine, temperance flowerdew, old wizard, party time, mare do well, gingersnap (i LOVE her colouring) and drinkie pie.
