URphid Sideboard Options

[Rodosti]

I have been running URphid for some time now, and the new combo decks based on Tendrils of Agony are a pain to deal with. My deck is as follows:

Main Deck
3 Wasteland
5 Island
4 Shivan Reef
4 Volcanic Island
1 Library of Alexandria
2 Island
1 Strip Mine
4 Ophidian
3 Morphling
1 Mox Sapphire
1 Mox Ruby
1 Mox Pearl
1 Mox Jet
1 Mox Emerald
1 Sol Ring
1 Black Lotus
2 Powder Keg
4 Fire/Ice
1 Fact or Fiction
1 Time Walk
1 Ancestral Recall
4 Force of Will
4 Mana Drain
4 Mana Leak
1 Future Sight
2 Control Magic
2 Misdirection

Sideboard:
1 Misdirection
4 Flametongue Kavu
4 Red Elemental Blast
4 Blood Moon
2 Hurkyl's Recall
 
I am thinking in adding to the SB Arcane Labs, but I cant really find room. Any opinions?

I'd Move the sideboard misdirection to the main for a fire/ice.
Drop 2 Flametounge Kavu.  With all the combo, aggro is taking a huge hit.  I wouldn't fear it that much.  Then you can sideboard 3 Arcane Labratory.
