Vulshok Factory

The trade this ramp rock offers is patience for a body, and the beauty of it is that patience costs you nothing. Every tap for red banks a charge counter, so the mana keeps flowing while the eventual Golem quietly grows: tap for the counter this turn, again next turn, and the sacrifice payoff scales with every turn the artifact sat working as a plain mana source. You never spend to charge it; you spend the mana it makes, and the counter is a free rider on ramp you were doing anyway. That sorcery-speed clause on the second ability is what keeps the payoff honest. It stops the token from becoming an end-of-turn ambush that resolves into a haste attacker nobody had sized up. The counter total is public, and the decision to cash out happens on your own turn, in the open. The haste is the reward for waiting: whatever it grew to, the Golem swings the moment it lands rather than telegraphing itself a turn early. It descends from the old idea of a mana source that eventually becomes a threat (the Mishra's Factory notion of a land that fights, ported onto an artifact you build up rather than merely animate), except here the size is banked over turns instead of fixed per activation. The real tension is timing: cash out early for a modest body now, or keep skimming red and let the Golem get frightening, betting the game lasts long enough to count.
