Jam

Description
This spell is only added to the players deck through certain spells, artifacts, or getting hit by certain attacks. It has no use on itself. Normally it's just there to fill up the players deck. All Jams are removed from the players Deck at the end of each battle.

Strategy and Synergy
The added Jams are always at the end of the deck. When there are only one or two Jams in the your deck, it's possible to shuffle and not having to cast them. The Jams are mostly added as a delayed cost for many spells. This delayed cost can be taken advantage of with multiple spells.

If the player has multiple Jam generating spells or artifacts, the player can use spells that fire more shots like Jam Slam or Jam Cannon. There also is Deck Slam that deals more damage for more spells in the players deck. This also includes the Jams generated this battle, that are still in the players deck. Generating Jams is no problem, due to increadibly powerfull spells like, that deal a ton of damage for almost no cost, but add Jams to the deck, or artifacts like that have strong effects, but add Jam to the players deck. There also are the artifacts that directly support Jam when played. Artifacts like or  make Jam helpful. Because Jam is also consumed on cast, artifacts that work with spells that are consumed, like can make Jam even stronger. Due to this Synergy, Jam pairs well with small engines. Also, there is the option to get 1 and skip through all the Jams, because the player doesn't have enough  to play the Jam cards. This works especially well with Bullethell Gunner, who starts with only 2.
