Groot So Brave and Stunning

This tree sacrificed himself so his friends could do what they needed to do to save the day.

But this punny name comes from the fact it runs Tackle and Never Back Down.

In addition to controlling the enemy, it packs a wallop by staying at max health and using Fighting Fit, Electromagnetic Backlash, and Dauntless.

Hard to Ignore helps to manage threat while Unflappable helps to draw more cards. Defensive Training helps get protection events back into the deck so he gets them more often per full shuffle, which is nice because they will be just as valuable or more so than his hero cards.
