These cards require a certain amount of all SP power in all four elements (for example, one card could require 100 SP of each element while another requires 200 SP of each element). These cards have a green serpentine border.
These cards add SP to the character's elemental powers until a player wins. Another card must be played right after a boost card is played.
These cards forces both players to participate in a challenge, usually involving careful aim of a spinner. If the player of the card wins the challenge, they can reclaim one of their lost weapons.
Similar to Golden Cards, Crown Cards are powerful, but burdened with a restriction; they can only be played if the player's spinner has a crown on it. These cards are kept face-up and can be used throughout the whole game (with the exception of Double Stars); but if the crown is removed, all face-up crown cards are discarded.
