Strike: Select an enemy follower on the field. Deal 4 damage to it and 3 damage to its leader.
This follower's name is also Lævateinn Dragon.
QWhat does "This follower's name is also [name]" mean?
AWhile the follower is on the field, it has the specified card name in addition to its original card name. Note that having the additional name doesn't mean it suddenly gains the same abilities as other cards with that name.
QCan I put 3 copies of Lævateinn Dragon (evolved) and 3 copies of Lævateinn Dragon, Attack Form in my evolve deck?
AYes. Their card names are different, so you can have up to 3 copies of each.
