Masterful Flourish (SOS)

Instant

Target creature you control gets +1/+0 and gains indestructible until end of turn. (Damage and effects that say "destroy" don't destroy it.)

Niche combat trick for black aggressive decks, but the single +1/+0 boost and indestructible effect are too narrow to compete with more versatile instant-speed removal or evasion tricks in competitive formats. Best suited for limited or casual strategies built around protecting key creatures through combat.
