Invocation de Chimeratech par overload fusion

Chimeratech : This monster cannot be Special Summoned except by Fusion Summon. When this card is Fusion Summoned, send all other cards you control to the Graveyard. The original ATK and DEF of this card are each 800 x the number of Fusion Material Monsters used for its Fusion Summon. Each turn, this card can attack as many of your opponent's monsters as the number of Fusion Material Monsters used for its Fusion Summon.

Overload fusion : Remove from play, from your side of the field or your Graveyard, Fusion Material Monsters that are listed on a DARK Machine-Type Fusion Monster Card, and Special Summon that 1 Fusion Monster from your Fusion Deck. (This Special Summon is treated as a Fusion Summon.)

Les monstres à retirer pour overload doivent-ils être uniquement dans le cimetière, ou uniquement sur le terrain, ou bien peut-on utiliser les monstre machines sur son terrain et dans le cimetière à la fois ?
