So, you've played many rounds of Hearthstone, right? This thread is for you to design your own cards that you wish would be in the game. Lore-compliace isn't strictly necessary but would be welcome. Here's mine for starters.
Intervention
Class: Paladin
Type: Secret
Text: When one of your minion dies, revive that minion with double the health and deal it's damage to the opposing hero.
Cost: 4
Lord Tresh
Class: Rogue
Type: Minion
Text: Battlecry: Gets your hero's current health. Replaces your hero next turn
Cost: 7
Stats: 4/3
Flush Out
Type: Cheat
Text: Put all minion cards on your opponents hand to the field. Quota 7< >3
Cost: 6
Note: Cheats are a special class of spells that have the chance of randomly replacing one of your cards as it is drawn and usually has a specific quota you have to satisfy before you can play it. Three special slots outside the standard 30 are set aside for these special cards. In the example above, the card Flush Out can only be used when your opponent has at least 7 cards in hand and you have only 3 and below.
