Gambit

Description
Hit random enemy tiles for 30 damage for each spell in your deck, instantly shuffle.

Strategy and Synergy
This spell has limited utility in most decks, as most shots from Gambit will miss. Thus, the majority of cards which deal more than 30 damage will outperform it. It synergizes with Shuffle Artifacts such as and  because it instantly shuffles. When the player has this spell they don't need to worry about longer shuffling time since this spell is always going to show up during a cycle through the deck. This allows the use of, Cataclysm, and Ramjet without the downside. Another tempting synergy would be with or, but spells like  and  should be used first, as they deal concentrated damage and cost less. In both pure Jam or pure Kunai decks, Gambit's utility is marginal. In Kunai decks it's a decent option but Kunai decks love to spam out all of their in rapid succession towards a specific target. Because shuffling always messes up their flow of Kunai, Gambit is rarely picked up for this build.

Gambit is most useful in the case of Viruspell, as unlike Kunai or Jam, which can get in the way and need to be Consumed in order to reach the cards which create them, Viruspell propagates in the deck on its own. During prolonged encounters, enough Viruspell can be built up in the deck for Gambit's DPS to vastly outpace what Viruspell spam could do on its own.

This spell can be used as a substitute for in decks that are based around constantly throwing out spells without thinking because it instantly shuffles. This allows you continually cast spells while keeping your DPS considerably constant. However, the use of could allow you to not break the flow of your deck which can be preferable to inflicting very little damage if your deck doesn't contain many cards.

Trivia

 * If using Midnight, Gambit will activate, but will not be Consumed, cutting the effect of Midnight off halfway.
