Of course we all want to push our decks to their maximal potential, even if we arn't building the strongest stuff in the game. We wanna see our darling favorites succeed, after all! As such, there's a few things I'm considering to adjust and tweak in this deck.
Swarmyard greatly adds to the flavor of the deck... but only gives colorless mana. In order to function at maximum efficiency, we'll need more green and black mana. So I'm considering swapping these for mostly Swamps later on (I actually only own 4 copies of Swamp currently). It'd be great to replace 'em with some more fancy lands like Verdant Catacombs or Cavern of Souls or even Boseiju, Who Endures... but those cards are expensive. Maybe some day in the future.
Grisly Salvage is another kinda hit-or-miss card. It gets you something useful for certain. But since it needs both green and black mana, something you might not have turn two, it sometimes feels like dead weight. Maybe it'll be better after I replace the Swarmyards? Who knows. This is another card I'm thinking to replace with more lands, since I feel it's not entirely uncommon to just get bad opening hands with not enough lands to do stuff with.
Hornet Nest and Scute Swarm are good cards that give use useful tokens, but don't REALLY quite fit the whole theme of this deck. They're one-offs we get out via Pyre, so I'd definitely be eyeing to replace them once new insects more suitable to this deck get printed. I'm always hoping for cool new bugs every set!
