(It doesn't need to have gone on the adventure first.) How much does Edgewall Innkeeper cost
As far as changes to make to the budget build of the deck, I'm happy with where it ended up in general, although as I mentioned before I'd drop the Intangible Virtue for another Honor of the Pure, otherwise you should be good to go
You need your opponent to have cast at least three spells for it to be worth the 4 mana you invest into it, which happens in a single turn cycle in Commander but takes far too long in Limited
Why yes, I would like to cast Wheel of Fortune or Mana Geyser out of my bin again
Whenever you cast a white-bordered spell, this creature gains double strike until end of turn
So, if I cast [c]Dauntless Survivor[/c] and it enters the battlefield, its ability will trigger, letting me put a +1/+1 counter on any target creature
