QWhen attacking using a follower with Twin Drive, if I reveal a Trigger with the first drive check, do I resolve the Trigger before or after performing the second drive check?

AYou resolve the Trigger first. For example, if you reveal and resolve a Draw Trigger with the first drive check, you will draw a card, put the resolved Trigger into your cemetery, then perform the second drive check. If you choose not to resolve the Trigger, you will put it on the bottom of your deck, then perform the second drive check.

QIf I evolve this follower with its Fanfare ability, can I evolve another follower using its evolve ability in the same turn?

AYes. Although you can only activate one evolve ability per turn, other abilities that evolve followers do not count towards this limit.

QIf this follower is summoned by an ability, do I need to pay its additional cost?

ANo. Summoning isn't considered playing, so you don't need to pay its additional cost.

QIf I don't have a Shadow Paladin follower to bury, can I play this follower?

ANo. If you can't pay the additional cost, you can't play this follower.

QDo I resolve Twin Drive before an opponent can play cards and abilities with Quick?

AYes. When attacking, all abilities that are triggered must be resolved before non-active players can play cards and abilities with Quick.
