Bring to Light

Converge turns the act of casting this into a manabase audit: the spell rewards you for the colors of mana you spend, not the quantity, so a base that produces all five hands you a tutor-and-cast for anything with mana value five or less. That ceiling is the constraint doing the work. A three-color cast finds a three-drop and lets you cast it for free; only a five-color cast unlocks the full range, up to a card as expensive as the five mana you paid to fetch it. The design is openly a tax on greed: it asks you to build the most fragile manabase you can stomach, then pays you in flexibility. What separates the effect from a straight tutor is that it both finds the card and puts it on the stack in one motion, sidestepping the target's own cost entirely (though the card it casts still has to resolve like anything else, and can be countered). That is why it has served as the spine of combo shells hunting a single enabler as readily as it functions as a toolbox for decks wanting a removal spell, a creature, or an answer on demand. The blinders are what keep it honest: creatures, instants, and sorceries only, no enchantments, no artifacts, no planeswalkers. You are paying a premium five-mana rate for the privilege of casting one card for free, and the whole bargain hinges on whether your lands can actually deliver five distinct colors when you need them.
