My friend is trying to finish off his modern deck and he needs:

1x Mox Opal
1x Steel Overseer
1x Steelshaper's gift

He has:
1x Thoughtseize
1x Kalonian Hydra
1x Steam Vents
1x Hero's Downfall
1x Textless lightning helix
1x Textless putrify
1x Zur the enchanter
2x Scavenging ooze
1x Xenagos, the Reveler

Plus more

Let me know if we can work something out.
