Escafil Summon

An Escafil Summon is a type of Summon introduced by HelixReactor. It is the act of "acquiring" cards in order to Special Summon an Escafil Monster from the Extra Deck.

Mechanic
For a player to Escafil Summon an Escafil Monster, they need to stack a number of cards from their Graveyard (not necessarily monsters; depending on an Escafil Monster's summoning conditions, the required Materials can also be Spell or Trap Cards) equal to their Endurance, face-down, then place the appropriate Escafil Monster from the Extra Deck on top of that pile.

Cards that are attached to an Escafil Monster are called Acquired Cards. Acquired cards are sent to the Graveyard if the Escafil Monster they are attached to would be used as a Material for an Xyz Summon, or any other Special Summon of a monster that requires its Materials for be attached to it.
