Conditioning Room

This is a truly fantastic card. On the turn you play it it costs one resource (itself) to heal one. If you never used it again that would be OK value. But in fact every turn you go into Alter Ego it will heal another one and draw a card out of your discard pile. You can use that card to pay for something, or hold on to it for your next turn, if it is a particularly useful event.

Then every turn you start in Alter Ego it will heal one and increase your hand size. Other than when you mulligan, you can't do much to curate the cards on the bottom of your discard pile but the healing and increased hand size alone are incredible. I would say this card is up there with Aamir Khan.

The other obvious comparison is Steve's apartment. It's a decent card, but it does suffer somewhat in belonging to a hero who otherwise has very little incentive to change to alter ego. — L3w15 7 · 2715
Agile Flight

As many others have already noted for some of Star-Lord and Gamora cards, this card actually cost 3, not 4. At 4 cost it is largely unplayable, and at 3 cost is a niche card that probably won't see much use outside, although the ability to split is nice. Compared to Inconspicuous and Giant Help, which cost 1 and 2, and remove 3 and 4 threat, respectively

Angela

This is an auto-include for Thor. Another 0 cost card to proc "Have At Thee!" along the lines of Defender of the Nine Realms with the upside of a 3 health, 2 attack ally. She is also tutorable with For Asgard!. Angela could also be useful for other decks running cards like Into the Fray who want to have a legal minion target most turns.

Damn right!!! Incredible for Thor! You don't mill the encounter deck as with defender of the nine realms, you choose from the 10 cards of the encounter... put in play a 2 hp minion, draw 2 cards, get rid of the minion with Angela and you still have a 2 dgm attack and a block next turn. Absolutely insane value! — neothechosen · 1670
Sorry it won't let me put more likes! — neothechosen · 1670
If there is a 2 health minion... — zephyr100 · 19
Bah! You could pick a 5 hp minion, attack with Thor too and it still would be a deal. And since this is aggro you'd probably include into the fray or relentless assault or there's always hammer throw... Angela still is incredible any way you look at it. — neothechosen · 1670
Booster Boots

This is missing the "Max 1 per player" designation that the card has.

Since I'm here, this is a great card that's really grown on me. I think it's a staple for survivability for the Guardians especially with Star Lord. Of course preventing 1 damage is great, and yea there's a chance you could kill a crucial card.

But the thing is you're still cycling cards. What's the benefit of that if you don't get the card in your hand, you may ask? Shuffling your deck puts all those big hitters back in your deck. For Star Lord, that means more Sliding Shot which is HUGE as well as more encounter cards from the shuffle. Rocket gets more weapons to cycle and really benefits from the survivability. It's less crucial but still useful for Gamora. Unfortunately doesnt work for Groot effectively since his counters interrupt before booster boots can trigger. But overall, great card.

Pulse Grenade

Looking forward to make this card valuable. My first thought is, put it into play, play Heimdall to rearrange the top of the encounter deck and then BOOM! Also, Scarlet Witch should be able to add a little magic to make things interesting...

This looks like binder fodder to me. Best case scenario, you're getting 3-5 damage for 3 cards. — Bastionfour · 2
Not wrong, and that's why I said "looking forward to making it valuable". Who knows what new cards to come might combine with it? On the bright side, in theory, it can already go as high as 6 dmg for 3 cards - 2 if you used the power in all of us to pay for it. That's better than uppercut, granted, less reliable. It also can be a target for mean swing. — neothechosen · 1670
