I think I like Duress since discard can pave the way for your easy quick wins combined with the pressure you can put on the board
Having a way for you to gain lore each turn that your opponent can't interactive with (outside of the small chance they are running item removal) is interesting
One potential issue with that: a lot of those characters are uninkable, just like Pan's Shadow here
Casting Thing in the Ice under Solemnity will give you a 0/4 that is ready to transform with your next instant or sorcery, giving you a huge monster and your opponent a headache
Id forgotten a crucial line of text, and Id cast a two mana spell that read, show your opponent youre a silly duck, then shamefully discard this. That wasnt exactly a great play experience, and its a consequence of incredibly rigid templating to enforce a specific play pattern
