For Challenge # 071

These have a little bit of cross-utility in that they both help you hit specific mid-range mana costs quickly, but mostly they're just two separate marginal mana-fixing abilities which aren't very exciting on a green 1/1, but may be useful often enough that a creature with both of them is playable.

I debated adding to the first cost to make it more symmetrical, but decided it would clutter the card more.

The first ability is rather similar to Skyshroud Ranger, which was fine and even got obsoleted by Sakura-Tribe Scout; so yes, I'd say adding an alternate sometimes-useful ability (Prophetic Prism) is a fine tweak. And they do indeed have no synergy even if you were able to untap it.
