Leyline of Hope
The Leyline cycle sells one promise every printing: pay full price at deckbuilding time, and the card is free on turn zero. This entry spends that turn-zero presence on the one thing lifegain has always struggled to translate into board advantage. Gaining life is famously inert: a defensive number with no offensive edge. Here the buffer becomes the win condition. Every point of incidental gain overshoots by one, so a deck built to gain in bulk climbs fast, and once you sit seven above your starting total the static anthem flips on and turns your whole team into a combat threat. Both the replacement effect and the anthem apply continuously as life comes in and creatures hit the board, so casting it free out of the opening hand means both halves are already switched on when the first drop of gain lands. That is the payoff for accepting the cycle's standing tax: drawn off the top instead, it is a four-mana enchantment idling while you scramble to gain, and by then the seven-life threshold is a much longer walk. The card rewards treating life total as a growing engine rather than a cushion, a build white has flirted with for years without a clean payoff. Here is the reason to keep counting past the point where the life was ever going to matter defensively.
