forest-glistenerelf-go asked: What are the chances of "mechanic E" standing for "engineer" and it assembles contraptions?

Let me try saying this a few different ways:

Contraptions are not in Kakadesh block.

Neither the word “assemble” nor the word “contraption” appears in the rules text of any card in the Kaladesh block.

The creature type Rigger does not appear in Kaladesh block.

Steamflogger Boss will not be a fan of Kakadesh block. Okay, maybe he will but not because there are contraptions.

There are no cards inside of a Kaladesh booster that allow you to assemble contraptions or are contraptions or care about contraptions.

Contraption caring cards in Kaladesh block? Zero.

I’m excited so many players would like to see contraptions because that means the day I crack and print them will make many people happy. That day though is not this fall (Northern Hemisphere).
