Dire Tactics

Unconditional exile at instant speed for two mana is a rate white-black almost never gets to touch, and the design pays for it by attaching a toll rather than a restriction. Instead of narrowing the target or slowing the timing, it hangs a life-loss clause on the caster's own board: control a Human and the exile is free, control none and you eat the creature's toughness in life. That inverts how premium removal usually costs out. Most efficient answers buy their rate with a concession handed to the opponent (a land off Path to Exile, a life gift, a token), a downside paid on the stack as the spell resolves. Here the downside is a deckbuilding decision made before the game starts, not a stack-based tax paid during it. Have a Human on the battlefield when it resolves and the second sentence never fires; skew tribal in some other direction and every cast becomes a real life payment against a big blocker or a fattened threat. Exile as the removal verb matters more than the flexibility: it answers indestructible bodies, recursion engines, and anything that would otherwise reward its own death, and it does so cheaply enough to leave the rest of the turn open. The Human clause is the whole tension. It rewards a specific creature type without demanding it, which lets the card serve as clean removal in a Human-forward shell or as a fallback answer in a deck willing to bleed for it.
