A / B / C

Abomination

• Gains a new ability when paired with High Evolutionary.

Absorbing Man

• Copies the entire text of the last card you played if it has an on reveal ability, meaning he will copy Electro and Space Stone’s on reveal abilities AND Ongoing abilities.
• Cards pulled by Jubilee, Sakaar, Grand Central, etc. are not played, Absorbing man will copy the card played before those effects triggered.
• Once Absorbing Man gets a different effect, his old one is gone. Meaning that if you play Odin or another Absorbing Man, the new effect will be re-triggered/copied.

Adam Warlock

• Adam Warlock’s effect triggers at the end of the turn. End of the turn effects trigger in play order, meaning:
• If I play Sunspot on turn one, Adam Warlock on turn 5 and the opponent plays High Evo Cyclops on turn 6, they will trigger in this order: Sunspot gains power, Adam Warlock draws a card if im winning the lane and Cyclops afflicts two of my cards in that location with -1 power.

• When Agatha is in your hand, your turn timer is greatly reduced.
• Agatha plays your cards completely randomly, but she will play herself if she can (to a random location).
