Such a toxic deck, pun intended...
Most of the cards in your deck have a base power of 2 or less, so I figured just throwing in Bast as an off 1-drop to Ghost is a solid pick, just makes your deck a little strong in case you need it, but of course, weakens Odin, but that's 1 out of 12 cards, so hopefully you're good :D
Ghost is a VERY powerful 1-cost card in this deck, having your opponent ALWAYS have initiative means all of their cards will be revealed first so Hazmat can reduce all of their cards and you won't have to worry about your cards revealing before your opponent.
Luke Cage is THE staple in all Hazmat decks, so there is no point in explaining Luke's appearance here.
The rest of the cards are here to be one giant play that'll be there to make your opponent just want to die...
IDEAL CURVE:
Turn 1) Ghost
Turn 2) Luke Cage
Turn 3) Zabu
Turn 4) Wong > Hazmat
Turn 5) Absorbing Man (copying Hazmat) > Beast; bouncing all the cards there to your hand
Turn 6) Wong > Mystique > Hazmat > Absorbing Man
*Alternative Curve*
Turn 5 Magik (This allows you to gain another turn to attempt the previous turn if you hadn't drawn it)
*Alternative Curve 2*
Turn 5 Absorbing Man (copying Hazmat) & Debrii
Turn 6 Odin (reactivating Hazmat and Absorbing Man (Hazmat))
