Gwen Stacy // Ghost-Spider

Impulse-style card advantage has always carried a countdown: exile a card and cash it before it evaporates, usually by end of turn. The front face erases that deadline, keeping the exiled card playable for as long as this fragile 2/1 stays on the battlefield. A one-shot dig becomes a standing option you can hold until the moment is right, and that patience is exactly why chasing the flip pays off. The Jeskai transform cost is steep and locked to sorcery speed, and that friction defines how the card plays: the mana is real, so committing to the flip means giving up something else on your main phase, and the body has to survive to get there. What waits on the back is a creature that feeds on the habit that made the front side worth running. Ghost-Spider grows a +1/+1 counter every time you play a land or cast a spell from exile, so every card you spend off that access literally sizes up the thing swinging at your opponent. Then the loop folds back on itself: remove two counters to exile a card and play it this turn. Watch the shift in terms, because it is the crux of the design. The front face grants patient, open-ended access held indefinitely; the back face converts that access into a burst you spend for tempo and reinvest as growth. Two halves of one engine, tuned to opposite tempos, one holding its resources, one burning them.
