First competition for me. Feel free to give me constructive criticism.

Horde Demons:

REMOVED

 Debated making this minion a demon, but decided only Warlocks really had them. Great synergy with the hero power ultimately resulting in the first card your opponent plays costing 2 more. Decent stats and able to stay on the board, which is why I made it an epic. First entry, love to hear constructive criticism. Thanks.

• Since many of this class's cards increase the cost of enemy spells, the enemy will likely have lots of spells in hand by turn 9. Thus, if played in combination with the right class cards (and Loatheb), the effect of Nepenthe will be devastating.
• The card is a gamble, though: largely useless against aggro, and even in perfect matchups against control/combo decks, opponents may not have many spells in hand when this card is played. In any case, timing is everything. Do you play the card on curve, or continue to increase the cost of the opponent's cards in the hope that it will further increase their hand size?
• Synergises well with the class legendary, Cho'gall, as eliminating the opponent's spells will force them to rely more on their hero power.
• Also synergises well with Twilight Destroyer, since without spells the opponent is more likely to have unused mana.
• Is somewhat thematic, as the clan worships oblivion and seeks a utopian void free of the chaos of life.
• Flavour text: "Nepenthe is excellent for... uhhh..."
