Plantosaurus or Magic eggs?

I really cant choose which of the two things i should waste my silver coins on!
What do you think guys? any suggestions? I also have ~600k silver coins and im kinda lazy to go to 1 million but it's possible.

EDIT: nvm everything is clarified now the 80k silver coins egg doesnt even give a legendary monster.. i'll just go for the orange eggs that cost 50 coins each

I guess going for a monster u know u that u will get it is better than a random chance of getting a momster u already have , althought plantosaurs grade D isnt good enough i guess , but its helpfull in clearing stages and maybe in pvp also
