wow split ult sub ryune is super super amazing! 7combo awakening and a FUA on a monster with an active that: 1) can burst kill; 2) activate FUA; 3) has haste; 4) can heal. Such a perfect dathena sub.
I mean, saria too, but I only have myr for a light leader and it's a little harder to burst when you need a cross and a FUA column on the same board (and active, potentially. That's 10 heart orbs you need)
