Playing with Thanos and surprisingly so far, this has been the most successful of any version I've played.
Rather than building around using Thanos and his buff from the Power Stone, it runs as a simple Ka-Zoo deck using the stones as extra power.
Struggles against high roller decks such as Lockjaw or Hela variants but can go surprisingly wide with 15-20 power in every lane at the end of the game depending on your draws. The flexibility of going wide with the typical zoo package + stone abilties and cantrip consistency along with the potential of dropping a Thanos are a huge surprise factor.
Elektra and Armor are both meta tech cards, Elektra for the amount of Sunspot and Ant-Man I'm currently seeing and Armor to counter Killmongers on my 1-drops or Power Stone.
Carnage helps to counter goblins as well as clearing your board of weaker stones(the only one that really matters at the end is power stone unless forced to go wide with a Zoo strategy)
A lot of the 1 drops can be changed out for playstyle preferences, or you could remove Kazaar and and a couple 1 drops for Sera and some 2 drops for a less 1 drop focused Zoo strategy.
