3. the really smart option: you bought 2 or more of the recently time limited offer: special engine boxes which give a rotary ⅔ of the time. Plus you get 14 more engines for the same amount (750) tokens) instead of 1 MT and 8 useless cards. I even got 2 RE, 4 V12, 3 V8 + a whopping 6 CREs out of 2.

added bonus: no need to cry you haven't got the required engines on some following events! :D
