Enlarge/reduce is probably one of my favorite transmutations. It leads to great stories. Like the time I used it to get a ride from my familiar. Or the time we were on a riverboat, and some kobolds tried to block our way by narrowing the passageway, and we all would've died a hilariously gruesome death had I not told my party my plan to make the boat smaller before casting the spell.
