Well, the synergy with fractal was supposed to be obvious but not overpowered.
The first lion you play is a 1|1 for three. But the next one actually gives you +3|+3 spread over two cards. After that, you're actually getting +5|+5 for three.
At the ninth card, you're paying three and getting +17|+17.
I think it's balanced at three, if not kind of over powered.
