I wonder if this is worth getting?
It's a problem I have. I've had to deal with it whenever I play MtG matches at Drafts and Sealed events in real life too.
Casual matches don't trigger fight or flight in me though, since nothing at stake. Hence why wants to play with you guys....
Also, once you beat the first campaign in Magic Duels, go straight to the store, get the deck builder, buy any boosters you can with gold unlocked, and you'll have enough cards to build decks.
