Counter: Tunnel vs Margrave
|Tunnel vs Margrave|
There are many ways to activate Tunnel during your turn, but the most satisfying way is when you are attacked. Using it as a defense against Trashing attacks is risky, as the Tunnels themselves can get trashed, but it is the perfect defense against a Handsize attack. It does not bring you back up to a normal handsize like Horse Traders or Watchtower, but it does gain you Golds. Once you've been forced to discard Tunnels several times, the likelihood of having three Golds in hand (and thus the ability to buy a Province) is quite high. This is especially true with Margrave, since you're allowed to draw an additional card first, but can work against any discarding attack.
Note that this does not work against Ghost Ship, as that card forces you to top-deck, not discard.
