If I play Master of Evolution which transforms a friendly minion to a random one that costs 1 more, but there isn't a valid minion in the game that costs that much, what will happen to my minion?

For example, if I use the Battlecry of this minion on a minion with a cost of 10, but there is no valid minion in the game with a mana cost of 11, what happens?

If there is no valid target, nothing will happen:

The battlecry will do nothing if a valid minion does not exist with the appropriate mana cost.

    Noted in comments on HearthHead, with one mentioning a blue tweet about it, but, link not provided. The interaction is definitely not difficult to test out on your own.
