For my first Card Face-Off I'm going to go with what I believe to be the hardest choice for control Druid: what 3 mana cost minions do you put in your deck.
1) Havest Golem - 2/3 minion with Deathrattle: summon a 2/1 damaged golem
2) Scarlet Crusader- 3/1 minion with divine shield.
Both of these cards share a common role: low cost minions that regularly take 2 of your opponents cards to destroy. Cards with built in 2 for 1's are arguably the strongest minions in Hearthstone; maintaining card advantage will win you more games than you realize simply by having more options than your opponent.
Harvest Golem's main strengths are the fact that he has 3 health, and the opponent never wants to spend a removal card on him as he knows it will summon the 2/1 minion, potentially giving you card advantage.
Scarlet Crusader's main strength is being able to deal 3 damage without dying on it's first attack, freeing up the opportunity to take out 2 opposing minions. Opponents are forced to "ping" the divine shield with either a low cost minion or hero power (Mage, Druid). In the early game, the opponent will have to waste his entire turn on removing the scarlet crusader, letting you keep tempo the following turn by putting out a real threat.
Both cards are low cost, high durability minions that force your opponent to use precious resources even though they want to ignore them and go after real threats. If your opponent does ignore them, they are prime targets for Shattered Sun Clerics, Iron dwarfs, and Mark/Power of the Wild.
Please reply in the following format:
1)Type of Druid deck you use.
2) Which card you would choose.
3) Why you chose it, and any other feedback.
I'll give my answer later before I post volume 2.
