Scout is great and all Robz, but these days what the forumers want to hear about is not ridiculously OP cards, but decidedly mediocre ones that are actually fun, in particular, everyone's favorite card, Watchtower. In this post I will answer any questions you may have about just how crazy the interactions these cards have with watchtower.
Lost City is a counter to watchtower-based strategies, of which there are many. Lost city is one of the few attacks that watchtower does not have a defence to. When you gain a lost city, your opponent is forced to draw a card, which makes their watchtower unable to draw as much on their next turn.
Magpie is great with watchtower. Suppose you play a magpie, it reveals an action or victory card, and you have a watchtower and second magpie in hand. Topdeck the gained magpie with watchtower, play your magpie and draw it, reveal the same card, rinse, repeat. In this manner you can gain the rest of the magpies in one turn; only two magpies and a watchtower required. That is true synergy.
Hero looks like a watchtower's dream come true; topdeck the next card in the sequence and play it the next turn, to cycle through the ranks even more quickly! But alas, this is not possible as the next card is merely exchanged, not gained. But don't worry, hero still has neat interactions with watchtower. With sufficient actions, you can play hero, gain a treasure on the deck, then play watchtower and draw one more card than normal due to hero decreasing your handsize. One of the cards you draw will be the treasure that you chose, too.
I look forward to exploring these exciting watchtower interactions with you all.
