I've seen debates on the pros/cons of "Power of" cards. When looking at leadership; all allies cost 2 or more resources to play. As more Leadership allies are added to the game, PoL only cements itself further as a must-have card in any ally-related leadership deck. It can be used for Make the Call or as payment for resource-specific cards due to the wild resource it provides - a significant advantage to all Heroes and against all Villains.
