A double striker with variable power is a design tightrope: the multiplier turns every point of that variable into two on the swing, so the card is either negligible or a clock, with very little middle ground. What resolves the tension is where the count comes from. Vivid reads colors among permanents, and lands do not carry a color unless something makes them one, so the number is built by colored bodies, artifacts, and enchantments rather than by the manabase. The four toughness stays fixed and durable while the power swells to match how wide your board's color spread has grown. That steers the card away from mono-color and go-wide sameness and toward decks that field a genuinely rainbow battlefield: colored permanents in three, four, five colors, not just the mana to cast them. Left alone in a mono-red shell it is a 1/4 with a wasted keyword, and that is the mechanic's demand laid bare: it needs a color count to justify the double strike, and beyond its own red it contributes little to building one. It is a payoff, not an engine, and it wants a board that already shows its colors before this ever comes down.
