Hermetic Study
Strap a continuous source of damage onto something that survives the turn and you get a machine gun: a creature that taps for one damage to any target, every turn, indefinitely, at instant speed. The model it follows is the Prodigal Sorcerer, the original "Tim," whose entire identity was that tap-for-one ability welded onto a body. This aura splits that creature in half and sells you the better part separately: it grants the ability to any creature you choose, which means you can hang it on something already worth playing rather than spending a card on a fragile 1/1. The catch is the catch of every aura: enchant a creature, lose the creature, lose the card, two-for-one'd by a single removal spell. That fragility is what holds a repeatable any-target ping at this cost in check. The reward when it sticks is a board presence that grinds out one-toughness creatures, finishes off planeswalkers, and chips at a life total without ever attacking. It rewards a host that wants to sit back and live: high toughness so it survives the ping wars, hexproof or protection so the aura cannot be answered for free. The effect has been reworked many times across editions, but the core trade (cheap, repeatable reach in exchange for sitting in a removal spell's crosshairs) has stayed remarkably stable.
