Anep, Vizier of Hazoret

The exert mechanic was built to make aggressive creatures pay for their upside with tempo, and this jackal spends that currency on card advantage rather than a bigger swing. Attack normally and it is a 4/2 trampler that pressures fast but folds to almost any blocker. Exert it and you exile the top two cards with a window to play them through your next turn, buying impulse-draw at the cost of leaving the board wide open on the crackback: the creature stays tapped, and a 4/2 that cannot untap is a liability against anything that wants to swing back. That trade is the whole tension. Red's answer to running out of gas has usually been the pure impulse engine (Light Up the Stage and the various "exile and play until end of turn" enchantments), which pays no board tax at all. Here the refuel is bolted onto an attacker that has to expose itself to earn it, so the fuel arrives only when you are already committed to swinging and willing to trade defense for it. The two-turn play window is what rescues it from being a pure combat gamble: cards you cannot spend the turn you exile still have a second turn to matter, which softens the flooded-draw downside that sinks lesser impulse effects. A brittle body, a real cost, and a genuinely useful reward, sized so that the reward only shows up when you accept the risk.
