Sundering Titan

Land destruction is usually a tempo play, a Stone Rain spent to set someone back a turn. This Golem turns it into a structural attack on the manabase itself, twice, with one symmetry that defines how it gets used: the trigger fires on entry and on leaving the battlefield. Drop it and you blow up one of each basic land type that anyone controls; kill it, bounce it, sacrifice it, and you do it all over again. That double-dip made it a Tinker target and a sacrifice-engine payload rather than just a fat beater. The body backs the threat: a 7/10 is genuinely hard to remove in combat, so the cleanest answers are exactly the ones that re-trigger its destruction. The wrinkle that makes it cruel is the "land of each basic land type" wording: it cares about types, not names, so dual lands and shocklands eat the trigger harder than basics do, and a greedy multicolor manabase hands it more targets than a clean two-color one. Players running mono-color or typeless lands shrug it off; players running Tundra and Steam Vents watch their fixing evaporate two lands at a time. The drawback (eight mana, vulnerable to bounce) is the same lever that makes it lethal, which is why cheating it in and flickering it has always been the point rather than casting it fair.
