Red Elemental Blast has no legal targets since this list is mono-red with no blue spells or permanents, so leave the full set at home. Ancient Grudge can pick off a Blood token from Voldaren Epicure or a Melded Moxite-made Robot if needed, but mostly comes in as a cheap cantrip-adjacent answer to any stray artifact while we lean on our existing lifegain and removal. Spellstutter Sprite adds a cheap flash flier that can block early Voldaren Epicures or chip in as a surprise blocker against the aggressive curve. Keep Prismatic Strands, Lightning Bolt, and Thraben Charm maindeck as they are the real answers to this matchup's burn and small creatures; this is mostly about trimming the slowest cards (Bitter Reunion, Melded Moxite) for slightly more relevant speed.
