I can't do it, but illusion spin is one of my favourites (it's also a fav of my first coach, who can do fab ones)
A skater I know has ina bauer into double loop in her program, which sounds cool
Actual ones that I can do, I like bunny hop, spiral, drag in combination, like attempting forwards-backwards drags, but only on smooth ice cause i always fall lol!
It's not really a trick, but the hip twists exercise from a high level field moves (I think it's some sort of back double three, jump into the air, twist your hips, land on the same foot thing...) looks really fun too!
Upright spin with a broomstick also good lol, that was for a show!
