It has virtually no proliferation, very few counter synergies, and two mono-colored historic cards
This makes it a very flexible addition for decks like Mad Party or Zoroark Toolbox
At the beginning of your end step, if you sacrificed one or more permanents this turn, Sawblade Skinripper deals that much damage to any target
To name a few, there is: Aurelia, the Warleader ~ infinite combat phases / Iona, Shield of Emeria ~ lock down all colors / Archangel of Thune ~ ramp +1/+1 counters fast / Archangel of Tithes ~ lock down attacking and defending of opponents / Chancellor of the Annex ~ counter everything / Exquisite Archangel ~ extremely hard to lose / Flameblade Angel ~ return large amounts of damage back to opponents / Gisela, Blade of Goldnight ~ take next to no damage and do extremely large damage / Sublime Archangel ~ extremely large damage when creature attacks alone Angel's Grace + Near-Death Experience ~ You can turn that potential lose into a win, as long as you have Near-Death Experience out on the field when you use Angel's Grace
When these two combine energies, they can launch formidable attacks against others, boosting them in power, status, and value
