Ognis, the Dragon's Lash

The trigger loops back on itself: this Lizard Warrior comes with haste, swings, and its own attack mints the resource that funds the next one. Every hasty attacker adds a Treasure, so a wide fast board matters more than any single creature's size. The economic wrinkle is the tapped clause. The Treasures appear when attackers are declared, well before damage, but they enter tapped, so you cannot cash them into mana that same combat. The ramp always lands one turn behind the aggression that produced it, which quietly steers the card away from surprise instant-speed mana and toward a build that hoards Treasures across turns and dumps them all at once. The Jund identity with hybrid pips does the framing: goblin-style token swarms, sacrifice shells, or a Dragon payoff pile that can spend a stack of Treasures faster than it accrues. What sets this apart from the wider field of Treasure-makers is what it keys off. Most reward casting spells or watching creatures die; this one reads combat itself as the economic act, which means the deckbuilding puzzle is the haste problem at scale. Solve it (mass haste-granting, or a board built to attack the turn it lands) and a single 3/3's swing becomes a board's worth of triggers, turning the attack step into the primary source of mana in the deck.
