Dominaria United draft sim

Cube composition: 4x of each common, 2x of each uncommon, 1x of each mythic and rare.

Packs: 1xmythic/rare, 3xuncommon, 10xcommon. As in retail, dual taplands just included at common. (No guarantee of 1 legendary per pack as in retail since it was too cumbersome, but odds are good anyway.)
