The best tactic I've heard is to keep a large stash of silver medals (over 1000) to upgrade cards outside of events and only use transmetal during events. The theory is it is virtually impossible to get a raid card from a silver so no need to crack them during events, and using transmetal during the hectic event period saves the ball-ache of cracking 300 medals to MTM newly found raid cards on day 1 when we're all desperating trying to one-cube anything that comes our way. You can then spend the down time between events using these stockpiled silver medals to MTM your tier rewards at your own pace!
