I know a critical hit can't be cancelled by a dodge token. If Luke triggers deflect by spending a Dodge token can he deflect critical hits?

Yes he can. Deflect happens as an armor save after all hit modifiers have been accounted (Crits, Cover, Dodgetoken, Keywords...). In this stage it doesn't matter if the enemy had surge, crits or hits.

Yes, the dodge token is only used to be able to use the abbility of deflect. Then you're just defending as normal (being able to cancel hits or crits) with the only change that you convert surges to shields and every surge makes 1 damage to the attacker.

A different way to explain it would be-

Dodge Token(s) is used instead and prior to rolling defensive dice against a successful attack, as it cancels 1 Hit per Dodge Token spent.

Deflect is more about canceling that 1 Hit prior too + adding defensive surge with a potential effect to the dice being rolled against a successful attack.

Great. Thanks for the info guys! I really appreciate it!!
