The 8523rd Cube

Lands you control gain "{t}: Add one mana of
any color"
When you cast The 8523rd Cube, each
player may pay {1}, if they do, each player may
draw a card, repeat this process until no players
pay mana.
Thank the creators of this divine cube, Torrez and
Arceus, for their wisdom shall be spread from this cube
to many lands and build a new world. It should go
better than the last 8522 cubes...
