A Justice League Dark Expansion:
Constantine: classic Constantine, where he's not migical but he knows how to manipulate magic and can use magical items (represented same as bat gadgets), reducing enemies dice rolls and rerolls, and also setting magical traps.
Deadman: can 'possess' enemy units and utilise them for a turn. Maybe can't physically take damage but if a unit he is controlling takes damage it reduces his stamina pool.
Swamp Thing: similar dynamic to poison Ivy.
Zatanna, Etrigan and others in not sure of, but I can work on it!
