Therefore, it requires no tributes to be placed into the field card zone, it cannot attack or switch battle position, it will be destroyed by effects that destroy spell cards like heavy storm but not monster destroying effects like fissure. You may treat it as a field card whenever the condition is fulfilled, so it can be searched by cards like terraforming and protected by cards like field barrier while it is treated as a field card, and summoned by monster reborn, etc while treated as a monster. It is not a normal nonster when not a field card. You cannot change its status from field card to monster while it is on the field or vice versa
