Affinity is an artifact-dense deck, so Dust to Dust is premium, exiling two of Myr Enforcer, Refurbished Familiar, Utrom Monitor, Baleful Strix, Cryogen Relic, or Giant's Boulder at once and crippling their affinity costs. Standard Bearer forces their targeted effects, such as Dispatch, to hit it instead of our real threats, buying time. Reckoner's Bargain doesn't target, so Standard Bearer doesn't affect it. We cut Phyrexian Walker and some Ornithopters since they trade poorly against Myr Enforcer and flying threats like Refurbished Familiar and Utrom Monitor. Keep Dispatch in, since with three or more artifacts of our own it exiles their biggest threats outright.
