Well, I probably would unless there was a spell that could really screw me over like fire storm. But I think the point is that the question of "Oh, for Hope it replaces 6 useful slots" is wrong because it would replace Light Towers, not anything else. Granted, a deck that runs for 6 Light Towers, 6 Beacons, and 6 RoL's would have trouble with deck space, but it would be able to keep a 12 wall of hope up. I would have to think about exactly what combos could be derived, but it opens up the possibility of mono-light Hope decks, or Hope decks that splash a mark and/or light pends for another element.
