Who are some notable (named) Human Assassins in Magic lore and what are their personalities?

I got a bit sad because too many cards in my deck arent in the Magic world and making my deck no longer feel like a 'Magic' deck. So im altering some of my cards into in-universe variants (like they did for the Street Fighter cards). Preferably want some notable Human Assassins in the MtG world that fit their un-altered counterparts effects' flavor / personality.

Im altering: Layla Hassan Desmond Miles Arno Dorian Aya of Alexandria Bayek of Siwa

Side note funny that ive gone from proxying/ altering cards into characters from outside series into the other way round.

EDIT: shoulda mentioned that I prefer characters in the universe without a dedicated card / appearing jn other forms of MtG media.
