Restoration Angel

Flash plus a flicker stapled to a 3/4 flier is the kind of stat-line-to-utility ratio that quietly reorganized how white midrange evaluated its four-drop. The body alone is annoying to attack into and a respectable clock; the enters trigger blinks a creature you control, re-firing whatever enters-the-battlefield effect that creature carries while ambushing attackers in the same motion. That flash window is doing most of the work: it lets you blink a creature in response to a targeted removal spell, dodge a sorcery-speed answer, or reset a freshly-tapped blocker by re-entering it untapped. The non-Angel restriction is the line that keeps it from looping with copies of itself, but it leaves every value creature in white's stable on the table, from mana dorks to anything with a useful entry trigger. What separates this from a slow value blink like Flickerwisp or a dedicated flicker spell is the assembly: the flash, the flier, and the flicker arrive on one permanent that demands an answer the turn it lands and rewards a board you have already built. It became a default white card in fair decks for years precisely because it asked nothing exotic of the deck around it: any creature worth protecting made the Angel better, and the Angel was already a fine card with the trigger doing nothing at all.
