Here is the current version of Tag 'n' Schlaghund:

3 Viral Breeding Ground
3 Tycho Extension

2 City Surveillance
2 Blood Cat
9 Schlaghund

6 Manhunt
5 Edgerunner, Inc., Temps
3 Project Consultants
12 Accounts Receivable

I've switched this around a lot, and I think it probably used to be
stronger. The deck can't really be built without the Schlaghunds. I
can't suggest an Uncommon or Common that could replace that card. There
was a period of weeks where I only traded for Schlaghunds.Oh, those
joyous days of yore!

Sparky is the one who started this. Right before Proteus came out last
August, he was trading for Schlaghunds like crazy. He knew Manhunt was
coming.

It's been mentioned before, but I think that the card titles for Manhunt
and Schlaghund Pointers got switched - they make perfect sense if you
reverse them.
