When Trickster sets aside Capital, what's the sequence of events? Do you still get 6 Debt?
I believe, Capital is being set aside by Trickster before its below line triggered, but dominion.games thinks differently
2 different things trigger from the same event (Capital being discarded), so you get to choose the order.
1. You take 6 debt and can pay off debt.
2. You set Capital aside.
You can do these 2 things in any order. However, it doesn't matter which order you choose, since neither of them can affect the outcome of the other.
It sounds like you were thinking that Trickster would set aside the Capital
instead of discarding it, but that's not the case. Trickster responds to when Capital is discarded.
