Conjoin

Conjoin or Conjoining is the act of placing an Evolute Monster underneath another. Evolute Monsters Conjoined to others are considered "Evolute Pieces".`

Characteristics
Like, Evolute Pieces are not considered to be on the field, and like , they can be Special Summoned back to the field, and are sent to the Graveyard instead of destroying the Evolute Monster it was Conjoined to. Evolute Pieces cannot be Disjoined as a cost to activate a card or effect.

Mechanics
During your Main Phase, during an open game state, you can Conjoin 1 Evolute Monster you control to another that you control, or You can Disjoin an Evolute Piece from that Evolute Monster, and Special Summon that Piece, unless that Piece is either or was not Evolute Summoned beforehand. You can only perform one of these actions once per turn on the same monster. That designated Evolute Monster will gain that Piece's E-Cs and effects (if any) while it has that Piece Conjoined to it.

You can Swap Conjoin by Special Summoning the Evolute Piece that was Conjoined to an Evolute Monster and Conjoining that monster it was Conjoined to to it.

An Evolute Monster with an Evolute Piece(s) can be used as an Evolute Material for an Evolute Summon by Conjoining it and its Pieces onto the new Evolute Monster.
