Pious Evangel // Wayward Disciple

The front face reads as a passive lifegain cleric that trickles a point off every creature entering, but the real machinery is in the flip cost: transforming demands you sacrifice another permanent, which converts the card from an entrance-triggered value piece into an aristocrats engine the moment you commit. That sacrifice clause is the hinge between the two halves. The Pious Evangel side wants a wide board and rewards each creature you play; the Wayward Disciple side wants those same creatures to die, and turning one identity into the other costs you a body you can spare. Feed it tokens, spare fodder, anything, and the drain half fires a two-point life-swing on every death you control rather than the front's incidental gain. The one-way flip and the tapped body it leaves behind are the structural cost. The activation being instant-speed is the underrated wrinkle: because the cost is a sacrifice, you can respond to removal aimed at another one of your creatures by feeding that doomed body into the flip, wringing its last value out on the way to upgrading the Evangel rather than spending a clean main phase on the transform. The asymmetry between the faces is the whole design: the front pays you for building a board, the back pays you for spending it, and the sacrifice cost is the toll you pay to switch which way the card is looking.
