Rogue Refiner

The textbook example of value stapled to a body without a tax. A 3/2 for three that draws a card pays for itself the moment it lands; the energy is the part that turned a fair midrange creature into the connective tissue of an entire mechanic-based deck. Energy in this era worked as a shared resource pool: cards spent it, cards generated it, and the archetype lived or died on whether you could fill the tank faster than you drained it. This was the cleanest deposit anyone got. No build-around, no condition, no downside; just two counters added to the reserve for doing something you already wanted to do. That is why it became the glue rather than a payoff. It asked nothing of the deck and handed back card advantage plus fuel, which let the genuinely greedy energy sinks exist at all. The draw-a-card-on-entry creature has a long lineage in blue and green, but most of those bodies stop at the card; this one quietly underwrites a second economy on the same trigger. Strip the energy out and you still have a playable two-for-one. Leave it in and you have the reason energy decks could afford to spend so freely.
