Yes, it comes with the downside of then drawing your opponent two cards but, depending on the board state, those two cards may not even be relevant
Starting with just one Adrix and Nev equipped with a Helm of the Host will give you two more during the first combat step you have them out
Designers may also choose to deal with these problem children by creating cards that directly combat their abilities
It would make more sense to have more tutors for artifacts in decks instead, since a tutor for artifacts can search for both Vehicles as well as other types of artifacts (hint: Boommobile can combo off with two other artifacts Cogwork Assembler and Panharmonicon)
With a combat bonus for swinging at your opponents, players are likely to take the opportunity to get some hits in
Sure some decks stand out more than others, but even their weakest ones (in my opinion) manage to pull their weight to make Commander 2016 a great product
