I'm using 4 honor of the pures insteaed, that way i don't boost my opponents creatures as well. I play mostly with friends, and they use theme decks, so using a coat of arms hurts more than it helps.

Ah, I do have coat of arms in my sideboard (this is my real deck), I just forgot to add them.
You know what could help you? coat of Arms. Eat rat would give 1+/+1 to each other rat. 20 rats out, = 20 22/22 rats.
