I only open packs as I receive potions from gaming.

I save up potions as I earn them to open packs to get more Gold and Legendary cards.

I was able to open up 66 packs with my saved potions. In those 66 packs I received 10 legendaries which is well above the 1.6% expected.

10 Legendaries in 66 packs

I keep track of each pack I open and like to see how I am doing against the standard expected number of cards per rarity.
Currently I am high on Legendaries and low on epic summoners and gold cards.

My Legendaries have been only 3 types so I will sell some to fill in the gaps of my missing legendaries.

Targeting moving from Mid Silver Deck to Full Silver deck.

I have started moving from a mid silver deck of level 3 summoners toward a full silver deck of level 4 summoners. I originally purchased 154 Riftwatcher packs and got most of my mid silver deck built. Purchasing another 154 Riftwatcher packs gives me 358 packs purchased which will give me one of each of the airdrop cards for the set. It will also be close to enough to bring my deck up to Full Silver(I hope).

An added benefit of purchasing at this time was the promo card give away for Winterfest.

Promo Card Arkemis the Bear

During the Winterfest sale you receive 1 promo card for each pack you purchase. I received the expected 151 Standard and 3 Gold Foil promo cards.
