Kaladesh visual spoiler, basic data and pricing.
Maybe the conspiracy is foiled too.
Any news when vehicles will be added? I checked and it says my database is up to date but can't find any vehicles from kaladesh.
I just found them, however the vehicle subtype isn't in the search which was my original problem. I don't see it being a huge mechanic but just wanted to bring it to your attention.
Those three are in the Welcome Deck 2016 "set". This "set" of 16 cards is indeed standard legal, Wizards' own Gatherer will confirm this.
The "W16" cards are found in the Shadows over Innistrad Booster Battle Packs, the free giveaway sample decks, and probably in 2016 Deckbuilder Toolkit boxes also. They will remain standard legal for as long as Shadows over Innistrad is legal, by that time there will be a Welcome Set 2017 in which some or most of these cards will appear again and remain in standard. Just watch the Gatherer for any doubts.
