Phlox - During the Activation Phase, you may disable this card to remove all Disable Upgrade Tokens from all of your other [crew] upgrades.
Li Nalas - You may disable Li Nalas to prevent 1 of your (crew) upgrades or Captain Card from being disabled this round.
Can I use Phlox, disable Li Nalas instead of disabling Phlox, and then Phlox's ability will re-enable Li Nalas?
Or can Phlox's ability re-enable Li Nalas, who can then imediately Disable again to prevent Phlox from Disabling?
