This is the mirror match, so bring in Wear/Tear to answer their copies of Blood Moon (which would strand our nonbasic-heavy manabase) via its enchantment-destroying half, and to hit Goblin Bombardment if needed. High Noon slows down their explosive multi-spell turns, restricting them to one spell per turn same as us, which is a fair trade since we can sequence around it with efficient one-drops. Thraben Charm gets cut since we're less likely to need graveyard hate against a mirror that isn't graveyard-centric, and Ephemerate is a lower-impact card when both sides are racing with removal. Keep Solitude and Galvanic Discharge in since they're premium removal against their identical threat suite.
