As Foretold

A delayed engine whose entire bargain is a ticking clock: it enters with zero time counters, climbs one mana value per turn, and lets one spell each turn slip in for free if its mana value sits at or below the current count. Read straight, that is a patient blue ramp piece for grindy decks, where by the time the counters are high enough to free a big spell, you could usually have paid for it anyway. What makes the enchantment dangerous hides on the cheapest end of the curve, not the expensive one. A spell with no mana cost has a mana value of zero, which means the enchantment can cast it for free the very turn it resolves, counters at zero, no waiting. The famous beneficiary is Restore Balance, a board wipe with no printed mana cost that was designed to reach the battlefield through suspend; As Foretold pays its instead and skips the wait entirely. Crucially, this is only an alternative cost, not a timing change: Restore Balance is still a sorcery, and As Foretold casts it at sorcery speed unless something else grants flash. That single interaction recasts the whole enchantment. Stripped of it, this is a slow value piece that rewards survival; with a stable of zero-cost spells, the once-each-turn clause becomes a recurring free Wrath or free Ancestral Vision while the clock keeps advancing in the background. The ceiling is dictated entirely by how many zero-cost cards you can assemble around it, not by the modest rate printed on the front.
