Cloudchaser Eagle

The design template for white enchantment removal stapled to a body: a flier that brings its answer with it, and the trade-off is the whole point. You pay four mana for a 2/2 and a Disenchant-for-enchantments on a stick, accepting a worse rate on both halves in exchange for never holding a dead removal spell in your opening hand. The catch is the targeting: the trigger is mandatory, so it always wants an enchantment to destroy. If your opponent has one, you have removed a problem and left a clock behind; if they do not but you do, the bird is forced to point at your own enchantment, which is a real cost in a deck that runs them. The enters-trigger does the work here, not an activated ability, so the removal is locked to the moment the bird resolves; there is no holding it up at instant speed, and rebuying it means getting the bird to enter again. You get one shot, when the bird lands. It is a clean, honest piece of design from an era that was still working out how much a creature should pay to carry a spell on its back, and the answer it settled on (a full mana premium and a turn of sorcery-speed commitment) reads as conservative now, which is exactly why the shape has aged so well. Wizards has reprinted the same logic under a dozen names since: bodies that fold a utility spell into an attacker so the card is never a blank.
