While the main combo finish involves enchanting an Exarch with a Twin there is a redundancy package which includes Restoration Angel that can interact with Kiki-Jiki, Mirror Breaker as a secondary plan to create infinite token creatures. One way the White splash helps in this deck comes from Wall of Omens which is part of the decks draw engine and especially abusive if you Twin in, but more importantly in a new meta which is partially defined by recently unbanned Wild Nacatl a four toughness two drop can be the sole difference between holding off a ruthless assault and holding on to combo the win. Additional draw comes from format staple Serum Visions with its Scry ability to not only draw valuable cards but also filter unneeded cards away and a one of Desolate Lighthouse allows you to dig through the deck to find answers or missing combo pieces. For removal with this deck having access to both Red and White we find the requisite format all-stars Lightning Bolt and Path to Exile both efficient and effective for their purpose. There is also Swan Song as a light permission suite to handle at an very cheap cost many of the problems that the deck might face and the token you give usually not problematic, with the removal able to handle most other problems. A full set of Snapcaster Mage are able to rebuy all of your used instants and sorceries to effectively double the amount of draw, removal and counters in your deck. As an alternate beatdown plan the deck sports a full set of Celestial Colonnade to bring the ‘death from above’ should the game stall into a draw out affair. Finally a one of Spellskite in the maindeck is there as a hedge preboard in the mirror and also a way to draw removal away from your combo creatures so you can go off unhindered when you’re ready for the kill.
