Mono Green Landfall mostly plays cheap creatures, lands, and enchantments, so Spell Snare has few profitable targets: it only counters mana value 2 spells like Shared Roots, and misses their one-mana Llanowar Elves and Sazh's Chocobo. Get Out stays in, since it counters their creature and enchantment spells such as Mossborn Hydra, Icetill Explorer, Earthbender Ascension, and Sapling Nursery. Traumatic Critique is too slow against a ramp deck. Our cheap burn like Burst Lightning and Impractical Joke can handle small creatures like Llanowar Elves and Sazh's Chocobo before they grow out of range, while Colorstorm Stallion gives us a proactive hasty clock to race their ramp-up plan. We want to be the beatdown here, since they have relatively little interaction for our Elementals once they resolve.
