For full neutral decks you can use
MO: Force of Nature, Fruits (which you already used)
SY: Blood Money
SK: Reckless Flurry, Patricidal Fury, (not sure if Blaze of Glory requires the discarded card to be SK)
ST: Deadeye Ambush, Invigorate, Guerrilla Tactics
NR: Uprising, Shieldwall
NG: Imprisonment, Tactical Decision, Doublecross, Imposter
There's no shortage of good leaders for neutral decks, it all depends on your goal for the leader, if you want control, pointslam, protection for engines, etc.
