This was the deck I first build when Symbiote arrived with a couple changes (I don't remember what I left out but the additions were Cannonball and Mystique). I finally got to infinite next day (05/Sept/2024). The deck works very nice.
You can't play Hazmat pretty soon as you will easily retrigger it at least once with Symbiote, and will allow a late Wong to make it 3 Hazmats. Hazmat is the main target of Symbiote, always the lowest card in the deck but in some cases you can also use it to retrigger Cassandra (though only interesting against Arishem or Loki), Sage, Silver Surfer or even a extra powerfull Gladiator (a 14 power Gladiator+Symbiote will destroy almost anything, specially if you used Cassandra before), though if you want to make sure one of them is specifically used you have to think in advance to leave that card alone enough or it will randomly choose one of those
All cards you could have a special interest to repeat with Symbiote are 2 or 3 power, so all of them can take advantage of any late 4-cost Wong in the same lane (remember to place Wong first and activate Symbiote after that, or even let it until the last turn if you wish)
If you have some space you will be able to repeat things like those even another time with a very useful Odin (so it's easy to get 6 Hazmats) or use it in a different lane to repeat for example a Sage + Silver Surfer.
About Cannonball is great to even let lanes completely empty, as with the help of Wong and Odin nothing has a chance.
