Blessing of the Nephilim
The payoff scales with a deckbuilding decision you have to make somewhere else entirely: the more colors a creature carries, the bigger this aura swings. On a mono-colored body it is a single white mana for +1/+1, a rate nobody pays. On a gold creature it is +2/+2, and on a five-color creature it would balloon further, which is exactly the trick: the card was built for environments awash in multicolored bodies, where a one-mana enchantment could read as a +3/+3 or larger pump that costs nothing but the aura's own card. That conditionality is the entire design. It rewards committing to a heavily multicolored board state and punishes nobody who reads the line and shrugs, because in a mono-color shell it does nothing worth a slot. The aura risks the usual two-for-one downside of any creature enchantment, so the colors it counts have to be plentiful for the math to clear the bar. It belongs to the small family of cards whose power knob is the color pie itself rather than mana value or a triggered ability, an honest expression of a set built around the friction and reward of gold cards.
