Psionic Bias?

[Yuki Akuma]

With core only+ expanded PH psionics are overpowered because thaere arent nearly enough spells that deal damage in the form that people want i.e there is no lesser acid orb where psionics gets Hammer. Once you expand the rules, psionics is incredibly unflexible and loses its advantage.

Yeah, but... psionics is better than magic at direct damage. Magic is better than psionics at other things, such as battlefield control. The two are not the same.
