Vodalian War Machine

A Wall that fights, but only if you're willing to feed it. The whole engine runs on tapping Merfolk: one activated ability turns off defender so the 0/4 body can swing, another pumps it, and you can stack those taps to convert a board of small blue bodies into a single threatening attacker. The defensive frame is the joke and the point. This is a shell that the rest of your tribe pushes through the front line at the cost of their own tempo, leaving them tapped out and vulnerable in the process. The death trigger is the design's act of conscience: every Merfolk you tapped to power the machine goes down with it, so a single combat trick or removal spell on the War Machine cashes in your whole investment at once. That clause is what keeps the card honest. Without it, you would simply tap your team, swing for a pile of damage, and lose nothing; with it, the more you commit to the attack, the more catastrophic the cleanup. The structure is deliberately asymmetric: the upside lives in activated abilities you choose to fire, while the punishment is a triggered ability that fires whether you want it or not, the moment the machine dies. It reads as war materiel literally consuming the soldiers who crew it. As a piece of early tribal design it is unusually self-aware: it understood, in 1994, that an effect this swingy needed a built-in tax, and it priced that tax in the bodies of the creatures that made it work.
