  We discuss new, theoretically clean strategies to determine the angle
$\gamma$ of the unitarity triangle from $B_d\to DK_{S(L)}$, $B_s\to
D\eta^{(')}, D\phi, ...$ decays, and point out that the $B_s\to DK_{S(L)}$ and
$B_d\to D\pi^0, D\rho^0, ...$ modes allow very interesting determinations of
the $B^0_q$--$\bar{B^0_q}$ mixing phases $\phi_s$ and $\phi_d$, respectively.
Their colour-allowed counterparts $B_s\to D_s^{(*)\pm} K^\mp, ...$ and $B_d\to
D^{(*)\pm} \pi^\mp, ...$ also offer new methods to probe $\gamma$.
