Thanks for the feedback on the cards LFN, but the most up to date versions were in the OP (eg contrarian has the clause, oppressor is a completely different card). I was just showing off some art.
I'm not sure what you don't like about Archer's attack. It's a spy that's guaranteed to delay a good card from the shuffle in the early game, while late game it's more like fortune teller. It's no Pillage but it's definitely going to hurt a little, and it's slightly different from the other "spy" attacks. Meanwhile the draw is either "+4 cards" or "+3 cards, and one of them is good", with a little bit of cycling (although that aspect is a "wash"). It could also be a "chancellor, then draw", but that's all the more reason to make it cost $6. Compare with Library and Journeyman.
Cell is purpose built for the 3 cards that give it out, which explore some common fan card ideas:
* Escape artist - +2 Cards, discard for actions (being a very mild attack should save it from being too good for 4, not good enough for 5)
* Patrol - A "when gain" Militia
* Oppressor - A "next turn" Militia
Escape artist is equivalent to urchin, while the other 2 are equivalent to militia (there's the card you didn't draw, and you can discard any other card to still have an Action), but there's a bit of versatility.
Your alternative is not a bad idea, but it's not the same card at all.
EDIT: Like I said in an earlier post, the new cards are Conflict (a single), Diggings and Prospector.
