Expansion / Explosion
: This brings us to the last card of the list, and boy, is this one a doozy. While not quite as insane as Temur Reclamation can make this card be, it is still extremely good in this deck. Both halves are relevant too which is an added bonus. Expansion can copy any other spell in the deck, allowing you to draw more cards, cast another removal spell, or even copy an opponent's removal spell to use on their stuff! Explosion is an excellent late game finisher made even more potent when
Niv-Mizzet, Parun
is on the battlefield, as he'll draw you one additional card, and give you double the pings! Just remember not to tap out casting it though unless you're sure your opponent can't kill Niv or they don't have a counter spell. Otherwise, that's a real feel bad moment. Explosion is also good enough even if you only cast it for an X of 2 or 3 too; you don't have to save it to do an extreme amount of damage in one go. If you cast for an X of 3, kill an opponent's creature and draw three cards, that's dang good on it's own. You need to remember that you can't copy Explosion with Expansion, because the CMC of
Expansion / Explosion
is at the very least 6 (it counts both halves of the card if it's a split card). Other than that, the card is right at home, and definitely a force to be reckoned with!
