Serum Tank draws you cards at the rate you advance your board — every artifact entering or proliferating the tank pays off immediately. In commanders like Xavier Sal, Infested Captain where poison counters and proliferate are already central, the tank pulls double duty as an engine piece and a payoff in the same slot.

Serum Tank belongs in Commander, full stop — the 60-card formats have faster, cheaper draw that makes a three-mana artifact with a slow charge mechanism uncompetitive in Legacy or Vintage. In Commander, the multiplayer pacing and artifact-heavy synergy decks give Serum Tank the time it needs to accumulate charge counters and actually fire. Oathbreaker is legal but the tighter game length makes it a marginal include unless your signature spell directly proliferates.

Current price
$0.39 bulk tier
At $0.39, Serum Tank is deep bulk — you're paying almost nothing for a card that pulls real weight in the right shell. Bulk rares rarely appreciate unless a synergy commander spikes demand, so treat it as a cheap pickup for now and don't expect the price to move.
