I was buying from galactic origin to build a saffira CA deck and bought 100 packs but didn't get any saffiras and I already have 3 senjus b4 this box came out.
So should I keep buying from galactic origin or start buying from this box ?
Your friends are misinformed.
Archfiend Emperor / King of the Swamp are two meta cards. The first is the archfiend deck ACE, it came incomplete this box ... and the second is essential to any fusion deck.
