On turn 3 it is a 4/2/3, if you play it on turn 4 it is a 4/2/4, and so on.

I think this is probably the best implementation of a "health equal to resource" ability, as it probably saves people the headache of dealing with a variable health amount linked to current resources. Furthermore, this is a great scaling creature, becoming beefier the later you play it - which should be a boon to melee-energy decks if they are going to deal with bombard+machinated combos from ranged energy players.
