Today I received the best Daily Quest rewards I've ever gotten.
Just the Legendary Black Dragon card alone would have made this one of the best daily rewards I've ever gotten. But when you add a gold foil Goblin Mech it really ups the stakes. I've been working on leveling up my Goblin Mech since it was first introduced. Now with one card, I've exceeded my present monsters level. I'll be looking to buy another gold foil Mech now to level this one up instead of worrying about collecting dozens more of the regular cards.
To top off the Legenday and gold foil cards, my rewards also included an additional two Rare cards. With only seven cards for my daily rewards any of these would have been good, but to get all of them at once is just fantastic!
