Against Grixis Death Shadow decks it kills Tasigur, the Golden Fang , Gurmag Angler, Street Wraith, Death's Shadow and Liliana, the Last Hope or Liliana of the Veil
Here are some of my favorite fighting cards for the deck: With your creatures being big and getting even bigger thanks to lords like Mayor of Avabruck they should be fine surviving most tussles, but if you want to guarantee they come out unscratched then you can run these damage prevention cards on top of Vigor
Keep in mind that these cards are universal effects, so both can be a slippery slope, but I feel like [casthaven]Muraganda Petroglyphs[/casthaven] is more tailor made for our deck, seeing as most vanilla creature dont see much play in Commander and I plan to have far more tokens in play than my opponents
We can then use another of Electrumites effects to destroy one of our own pendulums
from August 16-18
The only difference is that the copy doesnt count as being cast from a graveyard so cards like Increasing Vengeance dont get their extra benefits
