Only creatures with the following ability can change side
Treachery:
When the numbers of this creature's stack drop below 30% of its initial numbers, it turns to the enemy side. This creature cannot switch sides more than once per combat.
I think the tribal goblins is the only creatures possessing this ability.
As you can see it is based on numbers lost not tribal spirit, every creature with the ability "tribal spirit" can both lose and gain tribal spirit |
