I used to play Magic and I can kind of understand the idea of stealing cards to sell for money, assuming that was what the twins were after. Problem is, I was a kid back than and I now know it's only worth if someone is willing to pay. And how the heck will they explain acquiring a Black Lotus out of the blue? Plus murder is a stupid and lazy way of covering up your tracks.
Personally, I suspect it's more than just about the cards i.e drugs, debts. I miss playing Magic and I still admire professional players, but murdering a person over cards is just plain infantile.
