General Lee Oliver

Whenever you cast your first soldier spell each
turn, add {e} and draw a card.
At the beginning of your upkeep, add X mana,
where X is how much {e} you have. Spend this
mana only to cast a creature spell or activate the
ability of an artifact.
"Do you even understand what we're doing? Building
towns, protecting roads, running supplies - we're
carving out a frontier."
