Runes of the Deus
This Aura reads the color of whatever it lands on and pays out by identity rather than by what you spent to cast it. Stick it on a red creature and you get +1/+1 plus double strike; stick it on a green one and you get +1/+1 plus trample. The clever part is that the two clauses are not exclusive, and the checks are continuous: a permanent that is both red and green at once satisfies both conditions, stacking the +1/+1 bonuses and carrying double strike and trample together. That turns a connecting attacker into a damage funnel, and it makes the card a reward structure built squarely around the gold and hybrid creatures of its color pair, where a single body unlocks the whole effect through what it is rather than any decision at the time of casting. The catch is the one every heavy Aura wears: five mana committed to a creature, and a single removal spell answers both the creature and the enchantment at once, with no way to redirect the value once it has resolved. This is a build-around in the most literal sense, its ceiling gated entirely by how many of your creatures happen to be both colors at the same moment.
