Most Shrines have historically been slow-motion payoffs keyed to a phase trigger: check your count at the beginning of your upkeep or main phase and reap the reward then. This one abandons that cadence entirely and moves the accounting to arrival. The entry drain scales with the Shrines already on the board, so the card rewards being the last piece down rather than the first; the recurring trigger then converts every subsequent Shrine into a two-point life swing, one off each opponent and one onto you. That is the black-aligned reading of the archetype, which elsewhere leaned on card advantage, tokens, or incidental burn rather than a symmetrical drain-and-gain. The fragility is baked into the count itself: because both effects are board-state dependent, a single sweeper that clears your enchantments zeroes the recurring payoff, and the ceiling depends on how many other Shrines (which span a range of mana values, not a pile of one-drops) you can commit to a plan that pressures life totals slowly rather than the board directly. The one-mana cost lets it seat early as a cheap deposit into a compounding account, but the entry drain is also the deck's clean finisher when the board has stalled: an arrival trigger that bypasses combat entirely is exactly what a Shrine deck wants to draw once the count is high and the ground has gummed up.
