Hammerheim Deadeye
Red usually deals with flyers by burning them out of the air or staring them down with reach: damage, not destruction, and almost always pointed at a single creature rather than the whole category. This Giant rewrites that line. Its enters-the-battlefield trigger destroys a flyer outright, no toughness check, no damage to be prevented or scaled around, and that trigger, not the modest body it rides in on, is the entire reason to run it. Bundling a hard kill into a creature means the removal can be recurred, blinked, or replayed, an axis red's anti-air tools normally cannot reach. The echo cost is the toll for that flexibility. You get the creature and the destroy trigger cheaply on entry, but the following upkeep demands a much steeper payment or the Giant is sacrificed, which reframes the card as a tempo bet: a guaranteed flyer kill stapled to a creature you may not want to keep. Letting the echo lapse still nets you a dead skyfighter and a turn of pressure, so the card answers aerial aggression without forcing a lasting resource commitment. The whole design exists to hand red a clean, repeatable line against an attack vector the color was built to struggle against, with echo functioning as the price that keeps the recurrable kill from coming for free.
