This one is a bit more convoluted but has the advantage of not costing you the rest of your deck.
ET@Unified Kingdom to bring in Elishabiboo who places The Long Day on Soldier of God, the other Teal placer who places Stillness on Soldier of God, Asahel with Warrior's Spear who then bands to Soldier of God. This only works the once, because you still have to recur Unified Kingdom.
However, if you begin this combo by placing Unified Kingdom (which should be easy with the two placers you're using), add Lemuel to the mix and it's infinitely recursion via Philosophy or anything else you want to use for ET to recover.
In short, it requires 13 cards to use so it's large, but no one part of the combo is useless on its own. You have room for a fully-functioning Red-Teal-Purple offense (much easier to do than you would expect), the placing Heroes are grossly under-estimated anyway, and unlike the other combo you 1. don't have to wait until it's all set up to act (since you can use the combo even if you've already played the important enhancements earlier) and 2. it doesn't require a specific hand to be useful, only 10 certain cards in play or in your hand at the beginning.
Sure it's not a lock when you get it, but it's powerful enough and unobtrusive enough to warrant some play.
