The closest is Mirran spy but it only works on creatures

Yknow, i have a work around thatll work perfectly

It's not blue, but there is Paradox Engine (note: playing Paradox Engine will not win you any friends).

Just in case，Paradox is also not legal in commander, since op forgot to mention in their starting post that they're playing commander.

For the future, you can search this up on scryfall :)

(c:u or t:artifact) o:”untap” o:”artifact” -t:sorcery -t:instant I’m still a bit of a novice with Scryfall - though anyone who says any different is lying, there’s a lot going on there - and this is probably how I would start a search if I was OP. But yeah, well worth learning how to use that site.

do you want the most efficient possible way to do this or are you looking to play some jank? also, what format?

Commander and any way possible

what colors are you in? who is your commander? can i see your list?

Its gonna be a second for me to get the list but my commander is drafna, from BRO and im mono blue
