How you know you're on F.DS:
OP: "What do you think of this Kingdom with all Durations?"
Reply 1: Analyzes Kingdom, but includes the word "payload."
Replies 2-10: Debate the definition of "payload."
Back on topic, I do think that Outpost is strong due to all the ways you can set up your Outpost turn to be worthwhile. Enchantress is interesting since it hits twice with an opponent's Outpost, but doesn't attack if you play it on your normal turn when you also play Outpost. Also, all of the Duration effects mean you'll get a lot of your benefits prior to Enchantress hitting, which makes it less likely to seriously harm your turn, and a Duration hit with Enchantress doesn't stay in play, letting you get it back faster. So on the whole, I'd say Enchantress is weaker than normal here.
