Scathing Shadelock // Venomous Words

A 4/6 for five mana is already a wall most attackers respect, and this one doubles as its own recurring source of combat removal. Every turn cycle it recharges: at the beginning of your first main phase the creature becomes prepared, and while it's prepared you may cast a copy of Venomous Words, granting a creature you control +2/+0 and deathtouch. Casting it removes the prepared status but leaves the body intact, so the 4/6 is never spent or converted into a spell; it stands there and reloads. The economy is deliberately tight. You get the copy at most once per turn cycle, and firing it clears the state until your next first main phase, so the creature spends most of its life as a plain blocker waiting to charge back up. Because Venomous Words is a sorcery, the buff has to be locked in ahead of combat, and that sorcery-speed restriction is the tax a repeatable deathtouch grant has to pay. Granting deathtouch as removal-by-combat is a well-worn plan, but stapling it to a body that regenerates its own castability shifts the math: you are not drawing the effect, you are regrowing it. That is a genuinely different shape from flashback or adventure, both of which spend the card once and leave you with a graveyard. Here the same creature keeps offering the same charge, one turn at a time.
