Select up to 1 card in your cemetery and put it into your deck 3rd from the top.
Once on each of your turns, when you drive check a Trigger, deal 2 damage to each enemy leader and give your leader +2.
QWhen playing this follower's Fanfare ability, can I choose not to put a card from my cemetery into my deck?
AYes, you can. "Select up to 1" means you can select 0.
QWhen do "when(ever) you drive check a Trigger" abilities trigger?
AThey trigger when you resolve a Trigger revealed by a drive check. If you play a follower's Twin Drive ability and resolve 2 Triggers, any "when(ever) you drive check a Trigger" abilities trigger twice and become pending. Then, after you finish resolving the Twin Drive ability, you resolve any pending abilities.
