Dante

Dante's decks rely heavily on low MP action cards and low MP, high HP units to stall for MP so he can play his core units, namely 6MP Ibuki (Agility, Resonate: +1/+2) and 7MP Hsien-Ko (Resonate: +2/+2). 1MP cards like Foresight and Jackpot are pretty much staples of these decks because you can basically play them for free during Active Response phase.

Devil Trigger is a 3MP legendary action card that gives Flight and Agility to a friendly purple unit. Successfully applying this to Ibuki or Hsien-Ko can be pretty scary, especially if the enemy fails to properly counter this or wasn't able to put another flying unit to block your attacker.

Hidden Intent is a potent 2MP negation card that can negate action cards 5MP or less. The downside is halving your hero's Life so use this to protect your Resonate units against threatening action cards such as the black destroy cards or high damage red cards.

Due to the larger number of action cards compared to unit cards, you may encounter hard locks or have to cycle through your action cards until you get a playable unit.

Another weakness of Dante decks are the low number of units usually found on these decks, it will become a problem if your units gets destroyed or defeated in battle. However, if you can counterattack threats to your units through action card negation, halts, and weakening enemy attacks, your Resonate units can pass through defenses effectively.
