Scarlet Witch is one of the most powerful heroes in the game. Many people consider Hex Bolt her most prominent reason for that, but perhaps Molecular Decay is the real power behind the throne. This card is capable of doing 11 damage for four effective resources, hitting harder than Web Swing and Hulk Smash, provided you are extremely lucky. The difference is of course variance as often you will only get in the 7-9 range which is still very respectable and can just hit very hard out of nowhere. You almost always want to target the villain with this. The interesting thing about this card is that it scales up with the difficulty of the opponent, as more difficult scenarios usually have more boost icons among their encounter cards.

Am I crazy, or do I never see this card mentioned when people talk about how great damage increasing cards are for buffing multi-damage-instance cards? Such as Aggressive Energy, Warrior Skill, Float Like a Butterfly, etc. This card is already great, but it seems that buffs can really launch its damage.

Keep Up the Pressure is one combo I really have my eye on, since Wanda thwarts for 2, and it would allow her to summon this back from discard. Since it's a Side Scheme, you can "set it and forget it" if you happen to draw it early. Just wait until you cast the spell once, and then fish it back next turn at no cost but to thwart.
