Mono-Green Eldrazi relies on colorless artifact and land support (Urza's Saga, Eldrazi Temple derived tokens, small artifacts like Vexing Bauble/Haywire Mite/Soul-Guide Lantern); Meltdown at X=1 or X=2 blows up those cheap artifacts and disrupts their combo pieces. Our own Vexing Bauble shuts off any 0-cost tricks they might deploy and cycles late in grindy games. Our Thoughtseize and Fatal Push remain crucial to strip Emrakul or answer their early dorks, so the core disruption plan stays intact while we bring targeted artifact answers for their support pieces.
