Mahō Sentai Magiranger is a pretty fun show. Five siblings battle the forces of Infershia to save the world. Pretty standard sentai fair, but these are magicians.
So in order to defeat the villains, they have to go through trials and such to power up. I do wish they didn't use the cellphone motif that seems to be so popular now.
I'm enjoying the show. It's not Gekiranger or GoKaiger, but it'll do, donkey, it'll do.
