The point of this deck is to use the destroy package to destroy all of the infinity stones to free up the board space. The infinity stones are a great fodder for the likes of Killmonger, Deathlok and Carnage so you want to play them as early as possible in order to use them as a fodder to reduce Death's cost and advance Thanos.
The only stone you don't want to destroy is the Power Stone mainly because that stones enables your Thanos to become a 6/18 if you've played all of your other stones. Wave is also very essential to the list because she Reduces both Death's and Thanos's cost so you can cheat out death for a 0 cost if you've destroyed 4 or more cards and you can also play a 4 cost Thanos.
Chavez is here to help us draw into our other stones since you can only draw her on turn 6 so she won't mess up your curve.
