Replenish is a race against a combo-control deck with few blockers, so Pyroblast and Red Elemental Blast come in to counter or destroy their key blue spells like Attunement, Frantic Search, or Intuition before they can assemble the graveyard full of enchantments. Ball Lightning is weak here since it gets exiled by Swords to Plowshares for a tempo loss and does nothing if they just Replenish into Parallax Wave to exile your attackers. Earthquake is a sweeper against Opalescence, which turns their other enchantments into creatures (a Seal of Cleansing is a 2/2 and an Attunement is a 3/3), but it mainly serves as a surprise finisher since it also hits each player. Keep the burn suite maximized on their face since this matchup is a pure race before their lock comes online.

Pyroblast and Red Elemental Blast are premium here, countering Counterspell, Foil, Stifle, or Gush, and the Stifle mode is critical since countering it with a Blast lets Phyrexian Dreadnought's own sacrifice trigger resolve and kill it. Ball Lightning is a poor topdeck against a deck full of cheap counters and Daze that can simply tempo it out for free, so it comes down for more interaction. Overload can destroy Phyrexian Dreadnought itself since it's an artifact with mana value 1, giving a clean one-mana answer to their entire game plan. Prioritize racing fast and holding up Blasts on their turn to protect your own clock while disrupting their combo pieces.

Price of Progress stays in: more than half of Gruul Goblins' lands are nonbasic (Karplusan Forest, Rishadan Port, Wooded Foothills, Wasteland), so it can hit them hard. Lava Dart and a Cursed Scroll are trimmed because they are too slow or too small here. Pyroclasm is a strong sweeper against their army of small Goblins, such as the 1/1 Goblin tokens from Siege-Gang Commander, Goblin Lackey, and Goblin Matron, and Earthquake offers a scalable follow-up that can also go to their face. Both decks are aggressive with burn as reach, so holding removal that two-for-ones their Goblin swarm is more valuable than another one-for-one burn spell. Keep the core burn suite intact to race and use Mogg Fanatic and Seal of Fire efficiently against their small creatures.
