This allows you to exile any Bridge from Belows (as your creature died) before they go back into your opponents deck
As the only person in my playgroup with two mono-blue decks, this one is my favorite so far
Tuktuk Rubblefort With the small inconvenience that it's not colorless and it costs 1 extra mana, Tuktuk Rubblefort is a better version of Crashing Drawbridge as you dont need to wait a turn to give your other creatures haste
For example, looking at Belles Confidant our eyes are instantly drawn to the details that grace almost every surface
Jaheira, Friend of the Forest works in a very similar vein, being a difficult inclusion because of the Dungeons & Dragons property overlap, but turning all of your tokens into mana dorks really enables you to make some incredibly splashy plays
Both deck types want cheap spot removal
