Conversion Chamber

This is graveyard hate that pays you back, which is a rarer combination than the rate suggests. Most artifact-graveyard answers of this era simply blanked recursion or filled a tank; this one banks each exiled artifact card as a charge counter, then converts that stored opposition into a 3/3 Golem on demand. The design splits the work across two costs and two windows: the first ability is incremental denial, taxing a graveyard one artifact at a time while building a reserve; the second is the payoff, spending the reserve at instant speed to add a body to the board. That separation is the whole structural idea. You are not paying for a Golem; you are paying to deny an opponent, and the Golem is the deferred dividend on denial you would have wanted to do anyway. The friction is that both halves share the tap, so each turn forces a choice between extending the lock and cashing it out, and the converter only refunds what it first took away: no artifacts in graveyards means no fuel, and no fuel means no tokens. It belongs to a small family of hate pieces that try to be proactive rather than purely reactive, answering a problem on offense while leaving something behind on defense. In a vacuum the tempo is slow and the targeting narrow, but the dual-purpose framing is the reason it reads as a build-around rather than a sideboard afterthought.
