Exodus, Uncommon. Reconnaissance is one of those goofy little cards that people tend to overlook. Usually, in a white deck, you want your 1 mana cards to be either Savannah Lions or Path to Exiles—okay, that’s a drastic over-simplification, but it’s my column, not yours. You’re looking for something that can either smack someone in the face, let your stuff smack someone in the face better, or get rid of something that is trying to smack you in the face. Reconnaissance here is an excellent support card for that first type.
So this card just sits there, getting ignored for a good deal of the game. I’m not going to lie about that. But let me ask you something. Have you ever decided to attack an opponent only to realize too late that they had their biggest creature ready to block you?
You’re not alone. The beauty of this card is it’s a free take-back. “I swing with dude X. Oh, snap! You still have that thing untapped? I’ll activate Reconnaissance and remove dude X from combat”.
With this card in play, there is no such thing as a bad attack. As a primarily Commander player, I have to recommend this card for just about all Voltron-style (pile equipment/auras/counters on one creature and attack for lethal) decks with white in them. I personally have been running it in my Bruna, Light of Alabaster deck where it synergizes even more for a few years and I regret NOTHING.
