The Unkillable Adam Warlock

It is my opinion that Adam is secretly the best target for Symbiote Suit in the entire game. Adam can use the extra hit points to great advantage for soaking hits and charging the Bloodgem. The extra card from the Suit combined with the one from Sorcerer Supreme gives him a silly hand size of 7. His meager 1-1-2 statline badly needs a boost, and nothing else in his kit provides that. Lastly, the impact from the Hazard icon is reduced by Adam's 2 Cosmic Ward's that cancel treacheries. He gets all of the upsides, with a drastically minimized downside.

Your first deck pass can sometimes be a bit difficult to survive, focus on set up as much as possible with Soul World being your main target, the other cards you'll look for are Symbiote Suit, R4AF, and Defensive Conditioning. Use cards like Pip, Cosmic Ward, and Patriot to boost your survivability.

Once you're set up you'll have 25-30 HP, a 7 card hand size, an army of the best allies in the game, and you should rip through your deck to recharge Soul World in 2-3 rounds at the most. At this point you should be easily able to defend the table. Face tank any hits that come your way. Exhaust to defend for a friend and use Patriot or Pip to protect someone else.

Note that all of the allies in this deck are expensive, only Pip and Patriot are actually worth paying for, the rest are meant to be brought into play with Call for Backup and Summoning Spell.
