Mirage can attack for you on turn 1, untap, and then leave your opponent to attack whoever they want to--as long as it's Ultra Magnus, because he's Brave.

There are 3 Spare Parts in the deck, and the goal is to get one of those before your opponent gets a Bashing Shield. In an ideal situation, your Ultra Magnus would endure until the end of the round, opening the opportunity for you to make 3 attacks during the wheel turn. One from Ultra Magnus and two from Mirage. As upgrades stack on both characters, Battle Ready then would allow you to get attack bonuses for all three of those attacks.

Don't get me wrong--this is an untested jank deck. And Titan Masters untapping when the heads get deployed makes "wheel turns" an old phrase. And this deckbuild looks weak against one-tall decks, too. And against Sabotaged Armaments, Stable Cover, and blue and orange icons in general.

But hey! Other than that--this could be a lot of fun. :)
