Mayo's cloud bird was fast with good mobility. Had decent water control and some wind manipulation as well. Could generate mist that reduced visibility significantly, and could create currents that made opponents' movement more difficult.
But its defense was mediocre at best. If you could reach it through the obscuring mist, if you could force a direct exchange...
It fell relatively easily to short range assaults.
Matilda's beast, the tree turtle, was more robust in terms of durability but far less mobile. Could control the battlefield effectively by establishing dangerous zones that opponents had to avoid.
But it required considerable time to establish those traps properly. Required that opponents with elemental advantage over wood element, specifically fire users, didn't pressure it too rapidly before its defenses were ready.
