Today, when you order "Red One Way Forcing Deck (10d)", you'll instantly be emailed a Penguin Magic gift certificate. You can spend it on anything you like at Penguin, just like cash. Just complete your order as normal, and within seconds you'll get an email with your gift certificate.
Great for forces but also really good for making gaffed cards with (especially Torn and Rrestored
effects) or just using as duplicate cards in effects. You can also make you're own svengali decks
using a one way force deck if you want to.
I would recommend getting at least one of these
decks to put in your magic box because I find they always come in handy.
