[DECK] Type I Suicide Black ith Green Splash (unpowered)

Hello! I come from Germany and I understand a lot. But please answer in a simply english, so I can follow your commenst better and it makes the conversation between us more easy!
Now, here my deck:

I play Null Rods and Chains in the Mainboard, because I was allready 2 times in "iserlohn", the biggest Vintage Event in Germany. There I saw, that I MUST play them, because they helped me after Sideboaring against 90% of the Decks. So I had to cut 5 Slots, and that's very difficult:
