For light, I suggest getting the morning star. Other than that, Blessings seem much more helpful than Pegasus's, because to use Pegasus's we'd really need a specific deck for them (which I don't think we have). My suggestion would be 1x Morning Star and 5x Blessings, unless we want to grab another wings.
For time, I really don't know. We already have all of their cards except Hourglasses (not counting pends). We probably shouldn't get the hourglasses unless we have a deck in mind - some pends or pillars seem most useful. My suggestion: 1x Hourglass, 2x Pillar, 3x Pend, since it doesn't appear there's much point to grabbing the other cards.
