|When an enemy is killed, apply 3 Shell to the attacker
Shelly's stats are fairly poor; their true strength comes from the Shell they grant to attackers (this includes Shelly themself if they manage to kill something). For an offensive team, Shelly can provide a layer of defensive Shell to keep them alive. They also pair well with Chompom, who increases their damage based on the amount of Shell they have when activating, as well as other Shell cards.
Note that Shelly has a quirk to be mindful of: they will activate whenever an enemy is killed by any card on the field, even if that card is another enemy. In battles where friendly fire is involved, the player may want to be careful when playing them.
Despite Shelly's wording of "apply Shell to the attacker," Shelly will also trigger when enemies are killed indirectly, as long as a card on the field was responsible in some way for the final damage dealt. See here for more detail.
