Not sure if people have made the Stone Giant here as a unit so here is my interpretation on how a Stone Giant can be implemented here.
Type: Chaos, Giant, Heavy, Dead
Gold: 1750
HP: 1500
DPS: 25 (Hits only one target)
Speed: Same as Giants
Population: 10
Training speed: 40 seconds
Lore: A remnant of the giants who fought in the first Great War. Resurrected to now fight against the Order Empire, using statues of the old as Armor and Shield to protect it's decaying body.
Passive Abilities: Reduces damage taken from Light units by 20% and Heavy Units by 10%
Active Ability:
Taunt: The Stone Giant kneels down, roars and bashes it's broken shield, taunting all nearby enemy units to attack the Giant for 10 seconds. The Stone Giant cannot move during this period as well.
Cooldown: 60 seconds.
Let me know your thoughts.
