Unable to settle on just one design, Urza decided to create one versatile being.

Urza's Avenger

{0}: This creature gets -1/-1 and gains your choice of banding, flying, first strike, or trample until end of turn. (Any creatures with banding, and up to one without, can attack in a band. Bands are blocked as a group. If any creatures with banding you control are blocking or being blocked by a creature, you divide that creature's combat damage, not its controller, among any of the creatures it's being blocked by or is blocking.)

Fifth Edition

Fourth Edition

o0: Urza's Avenger gets -1/-1 until end of turn and your choice of flying, banding, first strike, or trample until end of turn.

The -1/-1 is not permanent. It lasts until the end of the turn as do the abilities that are granted.
