Stand and Face the Mighty Justice of Thor

The idea here is two-fold; thin out Thor's deck so his massive damage events come up a lot, and deal with his biggest weakness: resources. With a small hand size, cards like Asgard help, but static resources like Enhanced Awareness, Enhanced Reflexes, and Enhanced Physique, alongside his suite cards God of Thunder help to provide out-of-hand resources so instead of using cards to pay for other cards, you're able to play more cards which, effectively, gives him a larger hand size. Lady Sif and Daredevil are great allies that end up costing next to nothing about midway through the game and really help him both attack and thwart. Depending on the scenario, I'll swap out Quake for Daredevil, such as in a minion heavy scenario like Mutagen Formula. A Clear the Area can be swapped out for more Under Surveillance if needed to help with main scheme advancement, but chances are you'll be able to bring it back up quickly enough that it won't be a problem.

Your goal the first time through his deck is to thin it out and get as many upgrade and support cards as you can into play, while keeping the threat low enough that you won't lose to a bad Scheme boost. After your tableau is set up, you will be cycling his deck faster each go-through, but the access to events and ways to pay for them should help with most of the bad turns you get off of encounter cards.

Counterintelligence should almost always be popped for threat prevention. It should never stick around for too long unless you're staying in hero form in a solo game. Skilled Investigator was swapped out from Heroic Intuition as a 0 cost card that removes itself from your deck and has the potential to give card draw. It's also a great card to play on teammates if you have an off-thwarter. Under Surveillance's importance cannot be understated. It gives you that necessary breathing room in a solo game, and can be an entire extra turn in multiplayer. While these cards are good, they also might be the first ones up for cut when better options are released.

Beat Cop fits the deck design just so well it feels like it was literally made for this deck. Free threat removal every round + getting the card out of your deck and on to your tableau + ability to annihilate a minion in a pinch? Yes please. Stealth Strike (from Black Widow's pack) is another one that feels right at home in a Justice Thor deck. High damage to an enemy, and if it defeats one remove threat. Action compression is necessary in a low hand count hero like Thor. Clear the Area replaced For Justice! as a cheaper alternative (so more reliably able to use) and provides situational card draw.

for now, I'm testing out swapping Stealth Strike for Lay Down the Law, seeing if the reduced damage is worth the reduced cost.

Don't forget that his hammer Mjolnir is basically a free recursive resource until you start needing to attack. Ideally once you get going, you won't spend any time in alter-ego form if you can help it. Staying on Hero side is passively thwarting by not allowing the villain to scheme.
