This card generates for each ally you control (to a maximum of 3)

The Mad Titan's Shadow #18.
Band Together

This card has the potential to be totally dead and useless... however, certain heroes can make excellent use out of it even in its "dead" state when you have no cards in hand and it is a zero resource card.

Captain America requires a discard to use "I Can Do This All Day", making this a great card in a Captain America deck when he has no allies out but letting him act twice.

Alpha Flight Station is also a great card fueling a discard effect so that Carol can cycle her deck.

Finally, it can satisfy discard requirements for:

Wonder Man, using his good ATK score. SP//DR Command, for the card draw. and... Spiritual Meditation, if you make a Mystic Leadership deck, probably with Summoning Spell because you thought (correctly) that it looked cool.

Sorry to be pedantic, but this reflects more on the value of resource sinks that you've mentioned and nothing on Band Together. Literally every card in the game can be discarded to serve those effects. (Note it doesn't work with Adam Warlock because there are no printed resources) — Stretch22 · 542
I think his point is, when you are in the situation where Band Together is useless (no allies), you'd rather discard this otherwise useless card for those listed effects instead something else that might be playable. — erikw1984 · 6
I understand how it can feel better to discard a useless card than a useful card, but I object to the suggestion that it is good to run this just because you can discard it to these other effects. It is strictly better to have an option between playing a card and discarding it than it is to have it earmarked for discarding. Also, there will be turns where attacks are useless because there are no minions, or thwarts are useless because there is no threat. I want to minimize my likelihood of cards being useless. It should be acknowledged at this point that Band Together is exceptionally powerful to build around, and commenters in the other review cover this well. — Stretch22 · 542
My point was that the element of the card that makes this otherwise "bad" has viable workarounds in the hands of the right Hero. — Soulfire · 32

In my opinion worst card for a leadership deck that came out so far: if you have it in the opening hand it doesn't generate a resource as there might be no allies on the board. If I want to use it, I would need "big allies" which are more costly, but as they are more costly, the don't get played a lot in the decks; I still prefer the power of leadership, as it is more consistent for every leadership decks I've played

I have to disagree. I think this plays more like a Strength or Genius than a “Power of” card. Sure it might be dead in your opening hand (though with mulligan, your first turn is almost always fully efficient), but leadership decks should have no problem getting allies out. A lot of cards cost 2 or more, so we don’t even need “big allies” to make this a good card — Stretch22 · 542
I generally agree with you that power of leadership is better. Like most cards however there are edge cases where this does better. This cards resources can be used for anything instead of only for leadership cards. Also if you have 3+ allies out like when you are playing a "Voltron" deck where you are powering up your allies instead of killing them. — calderc23 · 82
So keep a Quinjet or two in your deck, hold it if you somehow get it in your opening hand, and keep one or two utility allies like Maria Hill with low costs on 'em so you can be sure to get at least one out in the first 3 or 4 turns. And play heavily on your Alter Ego side. At any rate, this particular "no ally" scenario is a pretty hard edge case, it's really tough to not have an ally in your first few turns even if you're playing an ally-thin deck; which, if you're playing Leadership, tf are you even doing? — KLSanchez · 20
Band Together is a great card in the right deck. If you build around a wide board of low cost allies (Blade, Stinger, Ant-man, Wonder Man, Kaluu, etc) and you focus on keeping at least 3 on the board at all times, then Band Together becomes far superior to any non hero specific resource in the game. I have a Captain Marvel deck that plays 3 copies of Band Together and builds up to a huge turn in which I see 15+ cards of a deck that has already been thinned down to 25 to 30 cards. I typically draw two Band Together in those turns. One pays for Avengers Assemble, the other usually pays for a Photonic Blast. It's much better than the basic 2 resource cost cards in that situation and it blows Power of Leadership out of the water. Power of Leadership might be more reliable in the early game (turn 1, maybe turn 2) but after that, if your deck is built and played correctly, then Band Together will generate more resources and is much more flexible because it generates 3 resources for any card, not just blue cards. I've had very few problems with drawing it turn 1 as I mulligan hard and almost always end up with at least one ally on the board. It's not as good in decks that have fewer allies on the board or are slower to get the allies out. — Ionichk · 10
Here’s the deck: https://marvelcdb.com/decklist/view/13542/captain-marvel-s-electric-boogaloo-undefeated-on-expert-2.0 — Ionichk · 10
It is great for a leadership deck with cheap allies and expensive events. Fill your board and then use this to fuel hard-hitting hero cards and big swings like Avengers Assemble or . . . Mass Attack? The one where 3 allies attack in the Spectrum precon. — OrionJA · 8
That's just incorrect. It makes the overpowered Leadership even more overpowered. When you have 2 allies (which is extraordinarily easy with Leadership) it's already a double resource, which will then easily be upgraded to a tripple, which will give you pretty much infinite resources. Completely broken card. And just because it's not good in the beginning, that doesn't make it a bad or even mediocre card. Super-duper busted and another reason why O will never use this busted aspect — Cogahan · 33
