FUN Guardians Deck.
Kitty: Play Turn 1, 2, & bounce with Beast on 3 making her 0 cost.
Rocket: Play on 2 if you have Beast and bounce back on 3 making Rocket & Kitty 0 cost.
or play on 6 with Gamora for a 16-power play.
Angela: Play on 3 (if no Beast) or 4. Use Kitty to power her up.
Star Lord: another potential bounce target.
Xavier: Play on 5 if you can win a lane easy. I usually try to setup Angela's lane to lockdown. or pair with a Zero cost if you have one. or play on top of Nebula.
Gamora: Play turn 6 with Kitty, Rocket, or Star Lord (if you bounced him)
Rest of the Guardians are replaceable & they're 100% better versions of this, but this is FUN.
Highly suggest Daredevil but... you could probably win those X lanes w/o him. (But I'm too Chicken)
Shang is almost essential as he is an alt turn 6 play when 16 power isn't enough. (And most of the time you won't have priority because of Kitty so Shang is guaranteed to hit.)
