Oversoul of Dusk

The protection package reads straight off the color wheel: green and white pay full hybrid cost for immunity to blue, black, and red, the three colors they are traditionally weakest against. A 5/5 body that cannot be Doom Bladed, Lightning Bolted, or targeted by anything blue is, against a deck without an answer rooted in white or green, a clock that is hard to interact with through the most common removal channels. Protection here covers damage, targeting, blocking, and enchanting at once, so the same keyword that walks past burn also dodges any black or blue removal pointed at it, and red's creatures cannot block it. What balances the power is the price of admission: five mana of green-or-white hybrid means it lands later than the aggressive bodies it overshadows, and its three protections cover none of its own identity. White's exile removal and green's fight spells answer it cleanly. The elegance is in the geometry: the card's protections name green's and white's three enemy colors precisely, turning the friend-or-foe shape of the wheel into printed text. Everything an opposing deck typically reaches for to kill a midrange threat is exactly the list this creature ignores, which leaves the two allied colors it shares as its only honest weakness.
