Doc Samson, Super Psychiatrist

The counter clause is the more famous half of this design, and it belongs to the additive branch of counter enhancement rather than the multiplicative one. Where Doubling Season and Vorinclex multiply, this works like Hardened Scales: each batch of counters lands with one extra of each kind, so a single +1/+1 becomes two, three loyalty becomes four. It is a flat bonus, not a runaway one, but it is unusually broad, catching every kind of counter across every permanent you control instead of a single type. The activated ability is where that breadth earns its keep. Because it produces mana equal to Doc Samson's power rather than a fixed number, the 3/6 body is a floor: tap for three mana as printed, or push the power up first (with +1/+1 counters or anything else that raises power, each such counter arriving one larger than intended) and watch the output climb. That is the spine of the design. Counters that actually feed power (the +1/+1s) make the ramp larger, and the extra-counter clause quietly compounds their pace. The tension it resolves is an old green problem: mana dorks scale poorly, and creatures that scale rarely produce mana. Here the two jobs are welded to one card, with the counter bonus greasing the growth. A 3/6 that makes three mana is a fair rate; a 3/6 that keeps stacking power-raising counters, each landing a step larger, turns into a mana engine that outpaces the turns spent building it.
