Good trade? (newbie here)

Personally I wouldn’t take it. None of the cards you’re getting are all that good, and Mawsonia is a pretty decent card, and fairly sought after by people that use Monsters of the Deep

If you want my opinion ...Since you are new your collection should be pretty small so it doesn't seem to be a bad trade .Now i would say do it if you think the cards you are getting are gonna be good for your decks
