Psimitar is a fantastic card for the Psionic archetype best wielded by Phoenix, Cable or Psylocke. Psylocke is rather interesting because you need to be careful about your Restricted slots as each Psi-Katana is also Restricted. You can avoid this being an issue by keeping one Katana fixed on the Knife side, but that takes away some of the powerful flexibility of Psylocke's identity set. Side Holster can fix this issue too. With 10+ Psionic cards in your deck, you should have a Psionic card to play almost every turn of the game, and it's a no-brainer how strong 2 free damage a turn is with no additional resource or discard cost. The eligible heroes can all thwart for two with their basic power, making Lock and Load a nice inclusion to help find this card. Nothing too tricky about Psimitar, just a solid card worth playing for each of the Psionic-heavy heroes.

You can use Call for Aid and have 0 Avengers Ally in your deck to get all copies of Digging Deep in the deck into your hand at the cost of 1 card + 1 Encounter card. The downside is this immediately triggers a deck reshuffle so all of your Digging Deep will be in the discard pile after the reshuffle and renders future Call for Aid not as useful until another reshuffle. The other downside is you have to play without any Avenger Allies which means missing out on some solid Allies like White Tiger, Kaluu, etc.

Note that if you have 2 Call for Aid, you can use 1 to trigger a reshuffle and 2nd one to get all Digging Deep but it would cost 2 cards + 2 Encounter cards which makes it not worth it.

As I understand first FAQ is no longer correct via "1.5" Rules Change. In a She-Hulk "Jennifer Walters, Rules Lawyer" deck there was a text "Forced; article 1: “If a forced ability requires one or more targets to resolve and it has no valid targets, it does not initiate.” Furthermore, in subsection A: “Any costs that would have been paid to initiate the ability are not paid.” The cost in question: discarding Superhuman Strength. So now we can keep the card in play provided we don't have a valid target for its effect." that implied, that if target would be dead because of attack (so there would be no valid target to stun during responce timing) or if the villain would have a Stalwart keyword (so they couldn't get stun counters) or if they would just already has stun counter (and without Steady they couldn't get second one), then Superhuman Strength would NOT be discarded (and you could do some crazy stuff this way, gaining two +2 ATK boosts)

Build Support is one of the most influential cards from Next Evolution due to its deckbuilding implications. In the average deck, it can cheat out a resource generator like Helicarrier or The X-Jet, for many heroes it can grab an even more powerful support like The Golden City or Asgard, and it introduces greater ability to build your deck around a specific single support like Web of Life and Destiny or Uncanny X-Men. Note that like Make the Call for allies, Build Support can bypass play restrictions on cards like Knowhere, which can make for some unique cross-team builds. Some of my favorite heroes to play this with so far are Cable, since it is a fantastic side scheme to put in at Setup, and Phoenix and Psylocke, who can clear it with one basic thwart activation even on turn 1. This player side scheme scales well to multiplayer too since everyone should have an eligible support, unlike some others that are more circumstantial. A great card to build around entirely or slot into existing decks to make them more consistent.

Quake punches above her weight. Her cost is excellent, and getting a 2 attack out of it if you so choose is strong. In decks that confuse the villain, Quake can be especially good as she can passively damage and kill remaining minions brave enough to still thwart. Given that most minions, generally, cannot scheme particularly well, it is often a worthwhile trade to take an extra scheme or two in exchange for the damage. Given that this is Justice, especially in solo an Under Surveillance and/or Counterintelligence can largely mitigate the dangers of having the main scheme completed while flipped down.

Overall, a high-value and cost-effective justice ally that can pile on the damage throughout a game.
