If possible, target a non-gold Unit with at least 20 Strength on the same row and set Base Strength the same as the Unit's Strength. Set Strength of the Unit to 3. If Hym gets damaged but not killed, damage the Unit instead. When owner has passed, change sides and set Strength to half the current Strength. If targeted Unit gets killed, Banish Hym. Banish when removed to the graveyard.
