Is there an efficient use for a surplus of Insects in Standard, Kaladesh to Ixalan?
Aside from simply attacking for the win on the following turn, you have many options:


Grant them haste with Samut, Voice of Dissent
Play a huge Majestic Myriarch and Fling him at your opponent


anothe option, without green: have both Decoction Module and Fabrication Module on the board when you cast the Hour, put all counters on one of the tokens and Fling that

Arcane Adaptation naming Zombie and drain opponent to death with Plague Belcher and a sacrifice outlet (such as Yahenni, Undying Partisan)


You can also drain them with a Wayward Servant if you can make it survive the Hour (and can play white too)



There are probably many more, but these are the ones I came up with in a few minutes.
