Boros Charm and Heroic Intervention might find a home alongside the Inspiring Call in this deck
First of all, it's slipperier than you might imagine at first: Too many great blockers simply can't block it at all, such as Commander Eesha, Silklash Spider, Wall of Denial, Will-o'-the-Wisp, Fog Bank, Mogg Maniac, Typhoid Rats, and many other great bodies
