Funny. Last night I put 0.03 BTC into https://bitcoinvideocasino.com/blackjack , played two hours of Blackjack, one 0.01 BTC, withdraw it back to Coinbase, and then used Blocktrades to sell BTC for Steem and buy a 20 (+1) batch of Orbs cards, with a nice sum of DEC left over for potions. Of course, I don't want to make a habit of this, but the bottom line is that the value of Splinterlands cards is MUCH more in the long-term than traditional gambling. I got four gold cards in those 21 packs, and that is PERMANENT DEC earning power, as opposed to playing blackjack...
