Blazing lion crazy increase?

Was checking elve to see mfr blazing lion value since its a dream pet, and about 3ish days ago maybe 5 max it was at 968 and I had a bat dragon and plans to add other stuff for it so it would be fair. I check today and mega blazing lion is at 1100! I’m so surprised it rose by nearly 150 value and I think that’s crazy.
