Rage

Jorbs

Rage, especially upgraded, will make some decent block for you in decks which are aiming toward Attack-heavy play. In theory, it might make infinite block later in the run, but in practice if you're playing infinite attacks in a turn you don't need block very much usually. A Rage+ can do a lot of work to getting you into that state later though. Note that Dexterity doesn't increase the block made by Rage, and that Panic Button doesn't prevent Rage from making block the next turn!
