Yugi Muto, Game Master

Whenever you cast a spell, choose one of the same colour once each turn—
{u}• Scry 1.
{w}• Gain 1 life.
{b}• Mill one card.
{r}• Put a shield counter on Yugi
{g}• Return target creature from your graveyard to the bottom of your library.

If all 5 effects are used in one turn, Yugi transforms.
