Looking for the last couple cards of my deck

I'm looking to finish up a Modern Rack deck and am a couple of cards away.

I'm currently looking for:

1x Ensnaring Bridge
3x Hero's Downfall
4x Surgical Extraction
1x Thoughtseize
1x Urborg, Tomb of Yawgmoth

and to a lesser extent I'm also looking for

2x Bitterblossom

No trade is too small for me and I'm willing to reasonably overpay if you'd be trading down.
