Evolution

"Evolution" is a mechanic that allows players to play enhanced versions of their units over weeker versions.

How it Works
Units with this ability can be normal called or rode like other units, however their true worth is displayed when they are placed over specific cards. Each cards Evolution ability informs the player what units that card can be placed over; this is called Evolving. As evolving a card is not considered to be Calling or Riding, so it is possible to normal ride a unit and then place an Evolution unit over it in the same turn.

When an Evolution unit is placed, the card that it is placed over remains under the evolution unit and is called the 'Evolution Origin'. The origin cards of Evolution units on (VC) are NOT considered part of the soul. When a Evolution unit is moved to another area (e.g. deck, drop zone, bind zone, hand), and Evolution Origin cards under it are sent to the drop unless otherwise stated by a units ability.

Using Striking Sacred Beast, Wingal Excelion as an example; this unit states:

Evolution-Grade 2 or greater card with "Wingal" in its card name

This means that this unit can be placed over any "Wingal" unit on (VC) or (RC) that is grade 2 or higher.
