Strength of the Harvest // Haven of the Harvest

The oldest problem with any Aura is the empty-board topdeck: the copy you rip off the top when you have nothing to enchant is a stranded card that does nothing. The modal land back half answers exactly that failure state. When your board is bare, the front half is dead weight, so the card flips into a dual that taps for either of its colors and gets played as a land drop instead. That safety net is what lets the front half be so greedy. Counting both creatures and enchantments you control means the buff scales with the two permanent types a go-wide green-white board is already flooding, and because the size is a static recalculation rather than a printed number, every creature token, every anthem body, every subsequent Aura pushes the enchanted creature up in real time. The two halves invert each other cleanly: a developed board is precisely where the Aura wants to be cast, and an empty board is precisely where the land mode saves the slot. Neither state wastes the card. The land entering tapped is the toll that keeps the swap honest, a small tempo cost paid for the guarantee that no copy is ever a blank in hand. It is a tidy expression of the design logic behind this modal land cycle: the mode you don't need becomes fixing, and the mode you do need pays off harder the longer the game runs.
