Starscourge Radahn

Trample
Eminence - As long as Starscourge Radahn is in
the command zone or on the battlefield, Deserts
you control have "{t}: add {r} to your mana pool."
A deck with Starcourge Radahn as commander
can have any number of cards named Desert.

Eaten from the inside, by the scarlet rot, his wits are
long gone.
