MTG Salvation

Will this play in Mono-Blue?

Probably not, though that's not too say it won't. It's a little too slow for mono blue tempo, you play it turn 2,turn 3 you can crew to attack, but it doesn't have any evasion, which makes it less useful, despite the card advantage.

because ofcourse a submarine that is silent can be blocked but a merfolk can't
wtf bro?

To be fair, it's not Invisible Submarine.

Very strange that a submarine wouldn't have some sort of evasion (Islandwalk seems to be the most obvious)

Card seems like Smuggler's Copter rebalanced into something less aggressively playable?

I'm all but certain that was the idea, but honestly I think the UU cost was enough to remove the most annoying part of Smuggler's Copter, which was how it was playable in literally any deck. A mono green deck playing the format's most efficient low cost flyer that also looted just wrecked deck diversity.

Of course, a card that probably won't be played at all was probably a bit far to go in the other direction, but I think WotC understood the main part of their mistake with Kaladesh vehicles and this cycle of colored vehicles is their trial attempt at making powerful vehicles that don't wreck the color pie.

U: Silent Submersible is unblockable until end of turn.

Would make this better, I think.

Yeah, anything like that. Complete design miss here.

...or even like "2U: Unblockable"?

Or, like any kind of evasion at all.

Inevitably part of the 0.25$ rare binder collection I think.

Good news, does get around some sweepers though.

I want to tap Emmara to crew this thing.....

in a perfect world.

Of each of the 5 colored rare artifacts in this set, this one is the hardest to make op
