Rhonas the Indomitable

The conditional that fences off attacking and blocking is the whole bargain: a 5/5 with deathtouch and indestructibility for three mana is wildly underpriced, so the design demands you already control a power-4 body before the God lifts a finger. That gate reads harsher than it plays, because the pump solves it from the same card: aim the activation at another creature, push it to the threshold, and Rhonas unlocks himself while turning a mid-sized attacker into a trampling must-block. The deathtouch is what makes the combat math vicious: a 5/5 deathtoucher that survives every block forces opponents to chump endlessly or eat the full hit, and the indestructibility means removal has to exile, bounce, or shrink rather than simply kill. This is the green member of a cycle of three-mana indestructible Gods built on an awakening condition, each color paying for its rate with a different gate; green's gate is raw power, fittingly, and green is also the color best equipped to flood the board with bodies that clear it. The activation can never point at Rhonas himself ("another target creature"), so the unlock always passes through a second permanent: you are committing to a board, not a single threat. The pump is repeatable, mana permitting, which lets the same engine that switches the God on double as a mana sink. It reads as a beater and plays as a board-state lever: hard to remove, painful to block, quietly able to end a stalled game on its own.
