Blade of the Oni

Reconfigure is the mechanic that lets Equipment stop pretending it is not just a creature in disguise, and this is the design at its most aggressive expression. Cast for two mana as a 3/1 with menace, it curves out like any early beater; the Equipment half is a second life the card grows into. Once there is another body worth suiting up, the reconfigure cost swaps that fragile 3/1 into a static buff that flattens whatever it is attached to into a 5/5 menacing Demon, base power and toughness rewritten rather than added, so it launders a token or a mana dork into a genuine threat while dodging the sorcery-speed sluggishness of hard-cast recursion by keeping the value on a permanent that already resolved. The tension it resolves is the classic Equipment problem: a creature that dies to a single removal spell early, or a piece of gear that is dead in hand with no body to hold it. Reconfigure collapses both failure modes into one card that is never wholly stranded. It is a threat when you are ahead on board and a resilient anchor when you are behind, and because the buff sets a flat 5/5 rather than pumping, it upgrades weenies far more than it does anything already large, quietly telling you which creatures it wants underneath it.
