Tips and Strategies[]
Mu Guardian is a fairly well-balanced card. It has a strength of 7, and while the cost to play it is costly, its reward effect is equally costly to the opponent. As Mu Guardian requires any 3 of your cards for sacrifice, it is easy to sacrifice 3 useless hidden cards to bring it out. If at all possible, bring this card out when the opponent has very few cards on the field (ideally none of them hidden cards).
