Scryb Ranger seems like a card that could do some useful tricks in addition to being a good surprise blocker against blue decks. However the card's playability relies on its synergy, and the following were my best ideas:

• Use with Mangara of Corondor to exile two permanents (untap with first tap on the stack)

• Use with Deathrite Shaman, Bloom Tender, Joraga Treespeaker or other mana producing creatures for enormous mana ramping.

Although the ramping could be strong and the double Vindicate is cute, I don't think either of these synergies are enough to make Scryb Ranger worth a slot in the deck. Are there synergies that I have missed, or are these synergies on their own powerful enough to see play in the competitive modern environment?
