I initially missed the potential of this card, but Patriot might be one of the very best allies in the entire protection aspect.

There are a handful of allies in the game with toughness and I find that they provide great value giving your hero multiple (usually two) chances to avoid a big hit from the villain. In my opinion a tough card is the most valuable thing an ally can have.

While Patriot doesn’t come into play with toughness he can gain them repeatedly over the course of the game. His ability has good synergy with cards that fish out minions, but even without those cards minions are likely to find their way into play often enough.

His 3 HP and 2 ATK means he can even provide good value while sitting on the table waiting for a minion to engage your hero.

This is an ally that you hope to play as soon as turn 1 and leave in play until the bitter end

I have a serious question about this card and Supresing Fire. What is triggered first? The overkill hit point check, or the healing from supressing fire?

Supressing fire as many upgrades aplied to enemies is marked as an interruption, so its effect takes place BEFORE the trigger, in this case, the attack from Full-Body charge, but at the same time it says that the healing will only take place AFTER you defeat the minion. In the other hand, Full-Body Charge doesn't specify when the hit point check takes place, is after defeating the enemy or before even appliying the damage?

It's a very niche card, and I see it in decks where it doesn't belong. You really need to consider what cards you are going to play with the three resources you could (possibly) get from Band Together, as opposed to Power of Leadership. It's not always the best for setup cards because you want to play those early before loading up on allies. It's not great to play allies because you can only have 3 out at once, meaning this can only give you 2 resources for an ally (barring Triskelion and other shenanigans). It's probably best for events you want to play late in the game (like attacks), or something like Avengers Assemble!, that want you to have a bunch of allies in play.

This is one of only a few cards that can make your hero the defender of an attack aimed at an ally without exhausting your hero. Seems like a solid way yo leverage your beefy 13 Hit points as well as healing with Altman Residence!

Hidden Base is a highly efficient tough status dispenser. We usually pay 2 ER for a single tough status, so 3 ER for three is tremendous. Moreover, the stocks on tough have continued to rise with the prevalence of steady/stalwart villains and scenarios that punish ally blocking. It takes several turns of flipping to access the value of all three tough statuses, and you risk effects that ping you for one or two damage that waste the tough before it can stop a full villain attack, but these problems can be alleviated with Ready for a Fights. Hidden Base is obviously great with Colossus, who can now consistently start with two tough statuses every time he goes to hero form. Some perfect defense strategies might find the tough statuses awkward, but I think Hidden Base is an automatic inclusion in base-ically (haha) every Protection deck.
