Soulcage Fiend

A 3/2 for three that spites the whole table when it dies, and that symmetry is the entire reason it belongs in an aggressive shell rather than a defensive one. The three life each player loses on its death only reads as a drawback if you are behind in the race; for the deck applying pressure, it is three guaranteed points of reach pointed at an opponent who is already lower, collected whether the creature falls in combat or to a removal spell. Who controls the timing barely matters: the opponent answering the body still helps you finish the clock, and sacrificing it yourself converts the 3/2 into a Lava Spike that strikes both players at once. The detail that elevates it past a simple burn body is that this is life loss, not damage, so it slides under prevention shields and damage-redirection effects that would otherwise blank the trigger. Symmetrical life-loss runs through a lineage of cheaper, splashier designs, but few have stapled the effect to a creature this cheap with a body that actually wants to attack. What balances the rate is that the cost is mutual: every point of reach it hands you is also a point shaved off your own life total, which rewards the faster deck and punishes anyone who tries to hide behind it as a blocker.
