Good day dear mates! 
Vruz is a Common rarity Dragon element Monster card (only the 5th Common rarity Dragon element card in the game), who packs quite a punch for only 2 mana. He is incredibly quick and can Sneak around to attack the last character on the opposing team before they even know what hit them! Even though he is pretty squishy, he can be tough to hit, and when he dies he bestows his spoils upon those around him, increasing their stats with the Martyr ability. Finally, at max level he also gets True Strike, so no enemies will be able to evade his attacks, even in Reverse Speed!
Here Vruz card abilities and stats
In my case accourding to my staked SPS amaount I was legal to buy just 9 cards just for 9 vouchers. So when sale has been started I thought it's good offer.
So I put 9 vouchers in the game and received all my 9 Vruz cards.But that's not all!
As a bonus on of them was gold foil card. And according to the current market price it costs 7.49$ So if to keep in mind that I spent just 9 vouchers and received in total more then 8$ it was win win solution for me!
Now it remains only to see how the card will show itself in the game. But I'll tell you more about that later!
That's all for now! stay tuned! Yours
