This is such a big asset for Shaper. With this, any breaker become amazing. Even bad breaker become ok. Note that you can use only one on the board, so only one breaker will benefit from it.
It pairs especially well with Engolo. Letting you make run on anything much cheaper. With it, Engolo will sometime be better to use than the proper breaker, depending on ice placement. For example : you encounter a Code Gate and push Engolo to strenght 6. Next ice is a strong Barrier (strenght 6, 1 subs), it would cost you 3 cred to break with Engolo and 5 creds to break with Paperclip.
But, that is not all. If you find yourself against a corp that use a type a ice more than the rest (for exemple, the corp mainly use Sentries). Then, by putting Gebrselassie on the sentry breaker, you can then pass ices for much cheaper, after paying the initial boost. Even better if you use card like Injection Attack, Pushing the Envelope or Lean and Mean.
Sadly, at 4 influence, this will not be splashed outside of Shaper. But for Shaper, it will runs cheaper for any corp archetype. In a Glacier, the one run you do will cost less, even against 4 ice deep server. In an asset spam corp, you'll be able to run multiple remote for cheaper.
And making runs cheaper is the same as having extra econ cards. A great card, for the very low cost of 1 cred. A real bargain.
