Vaultborn Tyrant is a green dinosaur that draws cards, gains life, and is hard to kill
I also think this deck is weird because there are two Demons with a blow everything up if this is cast clause in the cheat Demons into play deck
Explore unlimited card choices, pick the versions and art you like, and keep your deck box stocked with options without turning one upgrade into a bank conversation
Both of those abilities are great, but you also get to put another counter on a permanent every time you cast a noncreature spell
You can tutor up combo pieces like Helm of the Host or run it as an alternative to Go-Shintai of Life's Origin (all the shrines are legendary)
Its hard enough to deal with a seven, eight, or nine-drop on the first or second turn, but to have to do so against the absolute best creature in their deck against you
