Soulheart

Soulheart ( Sōruhāto) is an archetype of (currently) Level 1 monsters created by Taylor Gorrell with aid from AvzinElkein. All cards of the Soulheart Archetype are derived from elements of the cult hit video game Undertale, and when the story continues through commissions from any source, this Archetype will be used by the Dueltale incarnation of Frisk.

Play Style
The Soulheart Archetype plays a highly defensive game, using their protective effects in order to compensate for their low stats and trigger their Continuous Spell & Trap Cards. These cards are designed to give the player an instant win or a win without having to attack, relying on the Soulhearts' effects, as well as other support and their own effects, to give the opponent enough of a hard time so the win conditions can be achieved. While no cards of the like have thus far been made, Soulhearts are planned to receive members of multiple different monster types (Fusion, Synchro, Xyz, etc.), as hinted by "Virtutem" being a Tuner monster.

Trivia

 * The stats of the Soulheart Archetype, as well as those of a currently unnamed Archetype, are based on the two non-Neutral routes of Undertale. In this case, the Soulhearts are based on the Pacifist Run, where no monsters are to be killed at all; Frisk will always be at LV 1 on this route, which results in him being incredibly weak in battle with stronger monsters (which these cards being Level 1 with fittingly low stats reference), but his attempts to Spare monsters can end battles instantly (which explains this Archetype's reliance on instant/no-attack wins).
