Here's the first batch of 3-cost cards
Deflection
Action - Attack 3
+$2
Name a card type. Every other player discards a card of that type (or reveals a hand with none), then draws a card.
I really like this concept. What you must note is that they draw a card whether or not they discarded one. This suggests to me that the card is too weak as is, and I need some tweak to make it viable. Suggestions?
Mercenary
Action-Attack 3
+$1
Each other player either discards a treasure card or gains a curse
Another card I quite like. Probably it would work better as a 2-producing 4, in which case it's very comparable to cutpurse, but it's here for now. Potentially very strong if you can play it often though, so that's something to check on.
Rage
Action-Reaction 3
+1Buy
+$2
Discard 1 card
_____________________________
Whenever you discard a card, you may reveal and discard this from your hand. If you do, +2Cards
(Originally trashed it on the reaction instead of discarding it).
And I definitely want some reacting to discard in this set, but this as is is probably too weak. I'm worried if I make it a discard condition though (instead of trash), that you could really chain this up big-time. As is, it's a likely-worse version of woodcutter that you rarely, rarely want to trash due to it only bringing you back up to where you were at before the first discard. Maybe if it trashed for 3 cards?
Recycle
Action-Reaction 3
Trash up to two cards; +1 card for every card trashed this way
_______________________________
Whenever a card is trashed, you may reveal this from your hand. If you do, discard this card and gain a silver.
The set's early trasher which has a little late-game relevance and some interaction with itself and/or opponent's trashers. A little worried that opening double recycle could be too good, reacting to itself, but I'm not TOO hugely worried. Not a lot to say here.
Experience
Treasure-Reaction 3
Worth $2
Gain a treasure card worth at most the number of coppers you have in play.
______________________________________________________________
Whenever an opponent plays an attack card, you may reveal and discard this from your hand. If you do, gain a copy of that attack.
Well, I'm not really thrilled with the 'main' function of the card, but I want it to be a treasure, and I'd like to keep the cost 3. As is, this should really cost 4 or maybe 5, I'm aware. But I love the reaction function, though I don't actually think it's all THAT powerful... I have a few other ideas for treasures floating around, and I'll probably attach it to one of them.
Silversmith
Action 3
+1 buy
Every silver produces $2 more this turn.
Not a lot to say here. Probably almost as weak as coppersmith is.
