The next Selection Pack for Master Duel, The Frenzied Tuning, has been announced. The pack will be releasing on April 9th. The following cards have been confirmed:

Heart of Gaia (UR)
Master Peace, the True Dracoverlord (UR)
Bramble Rose Dragon (UR)
Kewl Tune RS (UR)

As a side note, this introduces the R.B. theme to the OCG. The name of the theme is read as “リボルボット” (riborubotto), likely meant to be interpreted as “Revolbot”.
