lorewise, who is/was the strongest character in the MtG multiverse?
new to magic, joined from the FinalFantasy release and very interested in the lore overall and how big it is, but i do need to know ehos the big powerful entity.

figured this would be the place to ask.
i recently started playing MtG, thanks to the introduction of FinalFantasy, i was always a huge fan of FF specially 8 and was curious about MtG. the merge of IPs made it easier to join you guys.

with all that said and me spending the last weeks going through every set in search of cool art cards and effects i am left with mainly one question.

who is the strongest entity in MtG? lore wise that is.
i see flavour text refering to many powerful characters, dont know yet if they all have cards but lore wise, for the sake of simplicity if you will, whos the strongest in the multiverse, ever?

thank you.
