Raging Felhound is my version of a controlled discard mechanic. The reason Discard Warlock isn't popular is because it can't control what cards are discarded. I'm also a huge fan of the gimmicky Cruel Dinomancer and Spiritsinger Umbra combo.
Although Succubus gains +2 stat points while Raging Felhound only gains 1 stat point, Raging Felhound has the advantage of choosing the card to discard. It is also possible that the game ends before Raging Felhound's effect comes into play, making it a vanilla 6/6 Demon for 5 mana.
On the phone, you get this nice little arrow button you can click to switch between the two hero powers, depending on which one you want to use. In this case, pressing the button would result in whatever other hero power you picked popping up.
On the computer, it's a lot easier - they're both there for you.
The intention was to create a more control-oriented Finley while still preserving the spirit of the card. This one offers you a lot more potential value than the original, especially when you aren't busy spending all your mana curvestone-ing and often end turns with mana to spare. Compared to Justicar, this offers more utility, allowing for both an offensive and defensive hero power, but at the cost of being less powerful outright (to get full usage out of the powers, you'd need to spend 4 mana instead of 2).
You have no idea how much I want to put a comma between 'Sir Finley' and 'the Pioneer', but Elise the Trailbazer doesn't have one, so...
A paladin weapon that looks simple but requires some explanation. Most adaptations are obvious, but to make sense, four affect your hero and not the weapon. Both Taunt and Cannot Be Targeted would affect your hero as long as the weapon is equipped, and both Steath and Divine Shield would affect the hero until the effect naturally expires. A stealthed hero cannot be targeted in any way, same as a minion, turning it into a pseudo Ice Block.
Two options, poisonous and +3 Attack, are about 1 mana too cheap. But Deathrattle and Windfury are at least 1 mana too expensive. The pure chance of the adaptation keeps the card from having the consistency to be too imbalanced.
