Daredevil, Man Without Fear

The Radar Sense clause is doing something subtler than the usual attack-triggered card advantage: permanent access to the top card is not a draw engine but an information engine, letting you know before you declare attackers whether the exile trigger will connect. That turns the attack step into a decision with no hidden variable. You swing, you have already read the card, and you know whether the body stays a 3/4 or grows into a 5/5 with the extra reach the +2/+1 buys. The vigilance-plus-haste line matters because it wants to attack the turn it resolves and keep attacking without tapping out of defense, so once it lands the exile trigger fires every combat while the peek keeps the outcome legible. What keeps the Hero payoff from being a dead conditional is that the exiled card is castable either way: whiff on the type and you still deploy the creature or cast the noncreature you just saw coming, so the trigger is never a pure gamble. The design resolves the problem that dogs every swing-for-value creature, which is committing an attacker before you know what you are trading for; here the top-card peek removes that uncertainty in advance, and the pump scales with how heavily the deck leans on the Hero type. It is a red-white aggressive threat that rewards knowing your own library's texture over raw density, since the card you flip is one you have already read.
