Spider-Man - Always Ready

With Inspired and Sidearm, Black Cat has a ranged attack of 3. Since she doesn't take consequential damage, Get Ready and Command Team provide great value for readying her for numerous attacks each turn. Target Practice can increase the damage of one of her attacks even more once she has Sidearm.

Goliath is also an excellent ally to ready in order to do 10-15 damage in a round (he can potentially be readied a second time thanks to the +1 health from Team Training). Rapid Response can bring him back to do another 10 damage when another ally ready is available.

When he's first played from your hand, Spider-Man (Miles Morales) is a great target for readying as well (especially to get multiple thwarts for 3). Maria Hill, Ant-Man, and Falcon are all good thwarters too. Maria Hill and Falcon are both good additional targets for Rapid Response thanks to their responses when they enter play. White Tiger is definitely a good replacement for one of the thwarting allies if you're against an expert villain with a stage number that allows you to draw 2-3 cards when she's played from your hand.

Factor in Swinging Web Kick as well, and this deck can deal out massive damage while still being able to handle quite a bit of threat. I hope you enjoy this deck!
