Together as One

Converge is the wrong-way-round of most multicolor payoffs: instead of rewarding you for casting the card with a rigid color identity, it pays out for the diversity of mana you can physically produce at the moment of casting. Six generic mana buys nothing on its own. The whole ceiling is set by your ability to feed it five distinct colors, at which point it becomes a Blue Sun's Zenith, a Fireball, and a life-swing chained onto a single sorcery. That is the tension the design leans on: the effect scales linearly with color count, so a two-color deck gets a mediocre split of Divination and a two-damage ping, while a five-color base of fixing turns it into a genuine one-card haymaker. The colorless casting cost is the tell. By pricing the spell in generic mana and moving all the constraint into the converge effect, the card asks nothing of your color identity to cast and everything of your mana base to matter, which makes it a natural centerpiece for the wedge and five-color archetypes that already treasure fixing for its own sake. It also splits its three effects across three axes (card advantage, reach, lifegain) so that the reward never feels flat; each additional color adds a card, a point of damage, and a point of life at once, and the payoff you value most depends entirely on the board you cast it into.
