Whenever Dragonhawk enters or attacks, exile the top X cards of your library, where X is the number of creatures you control with power 4 or greater. You may play those cards until your next end step. At the beginning of your next end step, Dragonhawk deals 2 damage to each opponent for each of those cards that are still exiled.
Flood the board with big-power creatures (4+ power) so Dragonhawk's attack trigger exiles a fat chunk of your library each combat, giving you explosive card advantage. You play what you can off the top, then any cards left exiled at end step burn each opponent for 2 apiece, so wide boards of beaters double as a recurring direct-damage engine. Win by attacking with a stompy dragon/big-creature team while the impulse-burn chips opponents out.
Massive recurring card advantage that's rare in mono-red, refilling your hand every combat
Doubles as a burn engine—unplayed exiled cards punish all opponents simultaneously
Cheap five-mana flier that demands removal yet provides value the turn it enters
Synergizes naturally with the big-creature aggro shells mono-red already wants to build
Trigger does nothing if you control no creatures with power 4+, so a stalled board cripples it
Mono-red lacks ramp and recursion, so losing Dragonhawk repeatedly to removal taxes you
Impulse draw can strand uncastable cards and burn value depends on not playing them—awkward tension
Vulnerable to board wipes that erase your power-4 creatures and your attack potential at once
