I don't hate graboids, in fact i used them a lot when farming top 50. But they are not strictly mono as they use time to evolve and i wanted to make a 100% mono (besides gravel, which is always going to take earth quanta anyway)
Antlions could make a very good substitute for Steel Golems i guess, but i like to try and lure AI attacks onto the golem, something i cannot really do with an antlion. Not to mention if a fire shield or the new thorn shield appears, your golem is gonna last a lot longer. It's all down to personal preference i guess and i will try antlions out and see if there is much improvment.
Gnome gemfinders... Ehh, i see where you're coming from as this deck is quanta starved. But i think that they're far too brittle, the damage is almost irrelivent (especially if they have shields such as permafrost) and an additional tower would be a far sturdier and generally better way of quanta generation.
Thanks for the comments guys! Keep 'em coming!
