This event creates a large limit on who is able to cast spells. Only cards designated as dragons can cast spells, but this does not confer spell-casting ability onto non-spellcasting dragons.
Therefore, while Dragon Magic is in effect, Sharla [4th-290] could not cast spells, but neither could Flashburn [DR-32], even though he is a dragon, unless he had an attachment that allowed him to cast spells, such as Viperhand [3rd-103].
Dragon Magic can be stopped by Calm [3rd-400] for individual players, or canceled for everyone with Limited Wish [4th-382] or Intercession [RR-48]. Such spells can be cast by non-dragons to counter Dragon Magic when first played, but not once the event has fully taken effect. Coupling this event with another, such as Dragon Raid! [DR-20] can make a dragon deck even more dangerous for a short time.
