Battlefield positions first, then bodies that survive, then cards. Energy is rarely the constraint.
The list is cheap. Eleven of its forty cards cost one Energy and only three cost more than four, so a turn is usually limited by what is worth doing rather than by what can be afforded.
That reverses the usual hierarchy. Positions come first, because the Legend only pays at a battlefield. Surviving bodies come second. Cards come last, and the deck is comfortable spending two of them to keep one defender alive.
