Commander Collection: Green copies of this are $10 but I sort of think thats because thats all theyre worth
Amethyst Dragons Explosive Crystal Adventure spell isnt really priced well for most Commander games, but I might consider it anyway in a Dragon tribal deck as a way to clean up a few small creatures in one fell swoop
Geth, Lord of the Vault, is a six mana 5/5 with intimidate, so it can only be blocked by Black Creatures or Artifact Creatures
Update: Thanks to some feedback, I've added some new challenging modes to the bottom of this article
This may find its way into Zombie decks that flood the board very naturally - Wilhelt, the RotcleaverWilhelt, the Rotcleaver, to be specific - but in my opinion, Zombie strategies are another extremely well-established archetype, so it's hard to make room for cards like this, even when they look really cool
Although it's a bit balanced with a very powerful card (Shriekwood DevourerShriekwood Devourer) and some very fun cards (Giggling SkitterspikeGiggling Skitterspike and Disorienting ChoiceDisorienting Choice)
