Lozhan, Dragons' Legacy

Two spell types that share almost no overlap in most card pools get stapled to a single trigger here: Adventure cards and Dragon spells, with the payoff scaling to the mana value of whatever you cast. The design bet is that you will lean hard into one axis or splice the two, because the damage is not a fixed number: it climbs with the spell that fires it. A cheap Adventure half pings for a little; a fat Dragon lands and simultaneously scorches something for five or six or more. The exclusion of commanders as targets is the discipline, closing off the free political shortcut of firing across the table at other generals and forcing the damage onto creatures, planeswalkers, or players. A 4/2 flier that dies to almost any incidental damage is priced as a fragile lever, not a threat: it wants to be protected and pointed, not raced. The trigger cares about casting, not resolving, which means the damage lands on the stack the moment the spell is announced, before an opponent can respond by killing Lozhan to shut off the payoff. That casting-time window is what elevates the card above an on-resolution trigger, turning every Dragon and every Adventure into a two-for-one on the way down.
