Flitterstep Eidolon

Bestow exists to solve the oldest problem in aura design, the two-for-one when removal answers the creature you enchanted, and the way this Spirit reads is a clean case study in what that solution buys and what it costs. As a 1/1 for two mana, it sneaks in for a single point, trivial on its own. The math gets interesting when you pay the bestow cost to graft it onto a creature already worth attacking with: the host gets +1/+1 and, more to the point, becomes unconditionally unblockable, converting a midsized beater into a clock no blocker can interrupt. The tension lives in the price. Six mana for evasion rather than raw stats is steep, which is why the aura mode plays as a finisher enabler rather than a tempo swing. What keeps it from being a conventional liability is the bestow safety net: if the host dies, the eidolon detaches and stays on the battlefield as a 1/1 rather than going to the graveyard, so removal on the host costs the opponent a card and still leaves you with a body. That body cannot reattach from play (bestow is a one-way trip; once it becomes a creature it stays one until recast), but it does mean the enchantment half never strands you down a card the way a plain aura does. A modest effect wrapped around a structurally tidy answer to why auras have always been a gamble.
