Mussolini, Hand Switcher

Eminence - At the beginning of your upkeep,
choose another player. That player is your ally.
That player may play an additional land on their
turn. If that player does, add one mana of any
color to your mana pool at the beginning of your
precombat main phase.
{t}: Choose a spell your ally controls. You may
add mana of any color to your mana pool equal to
1 plus the converted mana cost of the spell.
