Roasha, the Stone Mage

Ward {c}{c}
If Roasha is your commander, lands in your library cannot have colored mana symbols.
Wastes you control have "{t}: Add {s}, {w}, {u}, {b},
{r}, {g}, or {c}."
Golems you control are every creature type in addition to their creature type.
When Roasha dies, if it was a creature, return it
to the battlefield under its owner's control. It's an enchantment. (It's not a creature.)
