Jund Sacrifice grinds through removal like Requiting Hex and Deadly Precision, plus sacrifice-fueled value engines, so Origin of Metalbending's indestructible mode protects our key threats from both removal and combat damage. Warg Tactics offers similar insurance with hexproof and trample to push damage through their small blockers like Callous Inspector and Greedy Freebooter. Since they lack real countermagic, we don't need to worry about protecting spells, only creatures on the battlefield. We trim the weaker one-shot Snakeskin Veil and the marginal Elven Passage for these more impactful anti-removal tools.
