There are some heroes that play completely differently while they have a card from their kit in play vs not in play. Hawkeye with Hawkeye's Quiver is a prime example. Hawkeye's main problem lies in the fact that his Arrow events are what make him good, but his hero ability does nothing other than help you play your Arrow events, so his power level is up to the luck of the draw even more than most heroes. If you don't draw any Arrow events, then you might as well be playing with a blank identity; and if you draw too many of them, you'll just be spending them to pay for each other. But Hawkeye's Quiver solves both of those problems at once: you get to look for an Arrow event every turn you're in hero form, and you get to hang onto them separately from your hand for as long as you need until you play them. Overall a 100% high priority card to get into play any time you see it in your hand.

Very effective card in combination with Fluid Motion in a Wolverine deck. You play your first attack event for free with Wolverine's Claws, boost you attack and go for Quick Strike for good damages easily.

For a 4-cost in Marvel Champions we except something extra. Banshee is standard ally (3 cost, 3 health, 2THW and 2ATK) and the bonus to confuse a minion when thwarts. There is also a little bonus for being a Aerial character and the X-Men. This Justice ally can be played in any deck without requirments.

But... is this is worth almost full hand? I don't think so. Confusing minion (especially in solo) is not that great. Don't get me wrong this is effect that can be played immidetialy without any other cards in play. We got more dangerous minion, but still I don't see Banshee to be effiective in majority of decks.

Rating (A-C) B- Banshee is not the top ally in any meaning, but there is small chance that one visit in alter-ego can help to take a final strike next turn and freeze a big minion.

Since this comes up often: Touched is considered part of your deck, and counts towards the min 40/max 50 card limit (i.e. Rogue effectively has 16 character cards rather than the usual 15). Ruling here: hallofheroeslcg.com

Yes, Death-Glow and Touched count toward their hero’s deck sizes.

This is why the Deckbuilder includes Touched as a 'proper' card in the deck.

Since the Setup phase occurs after mulliganing, this means that Touched should be shuffled into your deck at the beginning of the game, and can potentially be part of your initial draw or (worse) your mulligan. It's only set aside via Anna Marie's Setup ability after that, meaning that you can mulligan into it and be forced to accept a 5-card opening hand.

...This is frequently house-ruled away. Do As You Will is the whole of the law!
