I dont get what point you are trying to make here. I would assume you are looking for critique? Wouldn't you want both mana and tormod's crypt with this deck? Pithing needle seems like it should be in the board, just me saying but I havent MD'd a needle when I have been playing trinket mages in eons. I would consider jumping on the band wagon of key vault shenanigans. The key is already easy for you to find and the vault could be a tutor target. There is infact alot of directions you could take with this. Lotus petal seems out of place as well. I do not what else I can say, as I dont have enough time to sit here and think about this more.
Critique please
I chose lotus petal over mana crypt due to its ability to get turn 1 mana drains online.
The pithing needle is over tormods crypt due to a heavy meta of tezzeret, so a pithing needle is more usefull for that as well as dredge, by using it for bazaar
As for the key/vault idea, I've been pondering that for a while, but i'm not entirly sure what to cut for them, when the main win is the salvagers combo
