Abigale, Eloquent First-Year

The enters-the-battlefield trigger reads like a gift until you notice the order of operations. First it strips a creature of all its abilities; then it hands back exactly three keyword counters: flying, first strike, lifelink. Point it at your own attacker and you have a two-mana evasive lifegain enabler. Point it at an opponent's creature and the transaction inverts: a horror with a graveyard-recursion clause, a menace commander with a game-warping attack trigger, or anything whose text is more dangerous than three keywords gets rewritten into a creature that flies, hits first, and gains its controller life in combat but does nothing else. That last detail is the point: the target does not become harmless, it becomes generic, and its controller still gets a lifelinking evasive body out of the deal. The keyword counters are the tell that this is a subtraction spell wearing an addition's clothes. Stripping abilities is normally black's or blue's job and normally a pure downgrade; grafting three keywords onto the shell is the softening that lets the effect sit on a small white-black body without reading as raw disruption. The counters also persist, so the target keeps its new identity for the rest of the game rather than snapping back the way a temporary lose-abilities effect would. The body itself is the cost of admission rather than the payoff, and the "up to one other target" clause lets the card come down as a clean threat when there is nothing worth reshaping and as a targeted answer when there is.
