The x3 and x5 bonuses expire. The stat on the card is the base which is then x3 or x5 during the event. In some events super rares (tier 4s) of a specific faction get x2 during the event, which also expires. This event (Fatal Furies) it is T4 Decepticons, it looks like that will be in the same in the next (Beast). So those are good to have around.
