Treva, the Renewer

The Bant entry in the Primeval Dragon cycle, five 6/6 fliers whose combat-damage triggers each ask you to pay mana of the cycle's central color for an effect themed to that color. Treva's payment is , and what it buys is life equal to the count of permanents in a single chosen color, across both sides of the table. That optional, mana-gated trigger is the structural tell of an early multicolor era's caution: the upside is real, but it taxes you the turn you connect, so it never compounds off a single hit the way a free repeating draw or burn trigger would. The body carries the card regardless. A 6/6 flier closes games on its own clock whether or not the ability ever fires, and against a board flooded with one color the life swing can decide a damage race outright. What dates the card, and what gives it its charm, is the assumption baked into the trigger: it pays well only in a field thick with same-color permanents. This is design from the years when committed allied-color play was still being coaxed into feeling like a reward rather than a manabase puzzle, a Dragon whose payoff scales with exactly the crowded, color-dense board states that era's sets were built to encourage.
