Glyph Elemental

Bestow was designed to solve the aura two-for-one problem: a creature that can climb onto another body and, if that host dies, walks off as a creature instead of dying with it. This one wires that safety net to a growth engine. The landfall counter accrues on the permanent whether it is standing as a 2/2 or riding as an Aura, so every land drop makes the enchantment worth more without ever risking a card. The elegant part is where the counters live. They sit on the permanent, not the enchanted creature; the buff clause reads them off the Aura and hands their sum to the host, so if the host dies and the Elemental drops back to being a creature, none of that accumulated size is lost. It simply reverts to a fatter body carrying the same counters. That reusability is the entire pitch. Most bestow creatures are a fixed premium you pay once; this one compounds across turns and survives the removal that normally punishes going all-in on a single target. It answers the classic fragility of Auras by making the growth a property of the thing you actually own rather than the thing you are hoping to protect. A modest starting rate that land drops keep raising, on a permanent that refuses to trade down.
