I actually agree with the tc. i mean, I know shards are really powerful, but when you think about it, they are a rare card that is virtually useless unless you upgrade it. So when you think about it, its basically a card that costs you 1500 electrum + A Lot of Luck. I mean, since it costs so much to begin with, why not let it pay off having just a little more and allow you to get that elemental mastery. In my experience, most battles are 1 of 3 things. You Slaughter your opponent, have healing skills, and get an elemental mastery (even if that slaughter comes right before a near death experience where you have 2 bonds and use rain of fire to amass a large skelly army to heal you), 2 you dont have healing, and you are only down 1-5 hp because they got that one lone mosnter out before you destroyed them, 3- YOu barely beat them, enough said (of course aside from losing). So If you can keep your health up that hi, then I think you deserve to have the elemental mstery out if you have the cards to heal your hp. And I do like the extra coins depending on how much extra damage you do to your opponent, unfortunatly I doubt this will be implemebted cause it would change the economy of the game.
