Ok... So I have read some places that you can have only 4 of the same card.. I know this.. Just wondering because some places have said you can only have like 4 magmortars in a deck in combination of Lv. X so example 2 magmortar and 2 magmortar X but not 4 of each. Is this true? Or can you have 4 magmortar and 4 magmortar X in your deck?
