My card for this week - a revamped (from a past contest*) Inquisitor.
Uses Exile from Menagerie and Storyteller's unique "play Treasures during Action phase, then pay your all your coins" mechanic.
Inquisitor - Action - $4
+$1
Choose one: Exile a non-Victory card from the Supply; or you may play a Treasure from your hand, then pay all of your $ (including the $1 from this) to play a card from your Exile mat costing up to $2 more than the $ you paid.
* amusingly, at the time, Menagerie had been announced, and this was my attempt to predict what the Exile mat could be used for. Now it just uses the exile mat.
Any feedback is welcome - I think this will definitely need some play testing to see if it's actually interesting, but I hope the ability to play and effectively gain your Exiled cards from this is useful. Without playing a treasure, you can play a $3 from your Exile, and it would just taker a silver to play a $5 card in Exile.
Turn X – Spend a buy and $4 to buy inquisitor
Turn X+1 – Play Inquisitor to exile a card and give $1. In this play it is terminal.
Turn X+2 – Play Inquisitor and maybe a Treasure to play that card from exile.
If the card you exiled costs $4 or less you could buy it at turn X instead of Inquisitor and play it both at turns X+1 and X+2, without the cost of a terminal space in turn X+1.
If the card exiled costs $5, you have to play a Silver at turn X+2. With this Silver in deck, you probably would be able to buy that $5 card at turn X or X+1 and play at turn X+2. The same for a Gold and a $6 card.
You don’t have to pay for the cards you gain with Inquisitor, but each time you need two plays of Inquisitor and a play of a Treasure. The final effect is of a $3 cost reducer which needs two plays to trigger, being one of them paired with a Treasure, and is vaild only for one card.
In general, it seems to me to be very slow to begin to produce benefits. Maybe it could even end up without produce them at all.
It changes a bit with other cards that care about exile, but would be better if Inquisitor would be stronger by itself.
