The only one-drop minion you should ever keep is Fire Fly. Will help you dip your toe in the water to see if the deck you are playing against is aggro, and give you presence on turn 1.
If you believe you're playing aggro Druid or Hunter and you have no coin, send Small-Time Recruits back too. Don't worry about Prince Kelseth aggro, you have a better chance at playing it than they do of high-rolling.
I’ve been working on the buff Paladin archetype ever since Gadgetzan came out. I think it was finally perfected with 3 necessary cards in KFT; Righteous Protector, Chillblade Champion, and Skelemancer.
Righteous Protector finally made Small-Time Recruits complete the set of necessary 1-drops.
Chillblade Champion replaces Ivory Knight for life gain, and also is a great finisher.
Skelemancer provides excellent punishment for board clears, the biggest weakness of this deck.
You can’t play spells and weapons, but this is a control deck. It’s a bit of a shift in thinking, but your minions do all the control.
Only known weakness is Big Priest, but great against anything else, including Warlocks, and especially Jade Druids. When your buffed minions go toe-to-toe with big Jades and win, you’ll get why. It’s a crazy high-stakes slugfest in your favour.
