Rick Astley the Eternal Ricker

Put a "Never Gonna Give You Up" token onto the battlefield under target opponent's control. Treat this
token as a 0/1 creature with defender and hexproof.

Whenever a creature controlled by an opponent
attacks you and Rick Astley, the Eternal Ricker is
untapped, you may tap Rick Astley, the Eternal Ricker. If you do, prevent that creature from attacking this turn and you may switch control of a "Never Gonna Give You Up" token with that creature.
