In Magic: The Gathering, Planeswalkers used to be incredibly powerful immortal beings before the Mending.
They were naturally extremely powerful after awakening, without needing to form numerous mana bonds or anything of the sort. My question is what made them so powerful? Where did the power come from?
I've heard that they had the ability to siphon mana directly from the Blind Eternities as opposed to filtering it through manabonds with lands. Did the Spark itself generate their mana? Something else entirely?
