Chase them down is arguably one of the first staple cards in M:CH, especially for certain Aggression builds. On the whole, Aggression lacks threat removal, and so having this option on hand is huge. Let's break it down:
-- The only cost is the card itself. 0 cost for 2 threat is very good by the standards of any class, even Justice.
-- Adds much needed threat removal to the Aggression aspect.
-- Requires a hero to attack and destroy a minion. In the core set, this makes this card not very playable for Iron Man or Spiderman, who both tend to do other things (Thwart and Defend, respectively).
-- Highly situational, and can end up as a dead card in the wrong situation or villain/scenario.
HERO SYNERGIES (as of Ms. Marvel pack):
-- She-Hulk: She-Hulk has two huge advantages when it comes to this card. For one, she is almost always attacking, and the other is that she is in Hero form nearly every turn.
HERO DYSERGIES (as of Ms. Marvel pack):
-- Iron Man: Iron Man wants to thwart whil in hero form. His one attack doesn't lend itself well to attacking, and he's got his gauntlets and events for that. Plus, he's gonna be in alter-ego for a lot of the game, making this a dead card.
-- Spiderman: Spiderman tends to defend, in part because of his awesome defense stat and in part because it accelerates his economy. He won't be attacking a minion that much.
Final Rating: 9/10
