Enduring Vitality

The Cryptolith Rite effect, fused to a body instead of stapled to a standalone enchantment: every creature you control taps for mana of any color, and the enabler is itself a 3/3 with vigilance already adding to the board it wants to be flooding. That combination is the pitch. A pure Rite does nothing until you have creatures; this one arrives as one, taps for mana on its own, and swings when it wants to. What makes it durable rather than merely convenient is the Glimmer death clause. When it dies to a sweeper or a spot-removal spell, it comes straight back as an enchantment, keeping the mana-granting anthem online. The trade is honest: once it returns it is no longer a creature, so it stops tapping and stops attacking, but the ability it hands the rest of the team survives intact. Do not mistake that resilience for immunity, though. On its front face it is an Enchantment Creature, so both creature removal and enchantment removal answer it, and once it flips to an enchantment the enchantment hate still lands. The interesting knob is the asymmetry it forces on the opponent: killing the body is a two-step problem, and the second step is removing an enchantment they may not have the answer for. It punishes the reflexive Wrath that usually deletes creature-based mana engines, and it slots into any deck built to go wide with small creatures worth tapping.
