Gideon's Sacrifice

Reads like a fog, plays like a fuse. Every point of damage headed at you or your permanents this turn (combat, burn, pings, even your own effects) gets funneled onto a single creature or planeswalker you control, and the redirect holds only while that chosen permanent stays on the battlefield. Because ordinary combat damage is dealt all at once, the naming choice cares less about durability than it looks: point it at a lone 1/1 and it will still soak an entire alpha strike, since the whole combat step resolves simultaneously before state-based actions ever check whether the martyr is dead. The redirect only lapses for damage dealt in separate installments later in the turn (a first-strike step ahead of the regular step, a burn spell cast after blocks) once the chosen body is already gone. That is where the instant-speed window turns it from a defensive shrug into a trap: hold it, let the opponent commit the swing or the burn, then funnel everything into a permanent that happens to be on the battlefield when the damage lands. It descends from the redirection lineage that shunts incoming damage onto a designated target, but the "all damage this turn" clause is unusually total, catching sources this kind of effect often lets slip. What holds the reach in check is timing rather than toughness: the sink has to still exist at the precise moment each packet of damage is dealt, or that packet resumes hitting whatever it was originally aimed at.
