I had the same experience. Used 40 Transmetals to level Razorclaw to 60. I like that the game won't allow you to waste them. Imagine needing only 5 to cap and accidentally clicking max and blowing 50 of them....that's too big a price to pay for fat fingers.

Seems pretty clear what is the best way to use them. MTM your raid cards, then stockpile them to use on your reward cards. I have Razorclaw MTMed, with Divebomb's robot mode about halfway to max. Chromia is powerful enough that I may use transmetals to MTM my 2nd one.
