Multiple Recycle Energy Summon
While most Energy Monsters require exactly 1 Recycle to be Energy Summoned, some Energy Monsters require multiple monsters to be on the field. In this scenario, the Recycles used for the Summon must be on the field.
The first archetype that incorporates Multiple Recycle Energy Summons is the "Silvent Evil" archetype.
Energy Card Zone
Is a new type of 5 card zones that stays below to the Spell/Trap Card Zones.All the Energy Material Monster are placed on the Energy Zone that will be in the same column as the Energy Monster was when summoned(or any closest Energy Card Zone, if that zone is not available), being linked to it.When the Energy Material Monster are placed on the Energy Zone, a number of Energy Counters will be placed on that zone equal to the level/grade of that monsters, and can be used to use the Energy Monster effects (or sometimes, another card effect, instead)
