Descent of the Dragons
The transaction is the whole point: you destroy a battlefield's worth of creatures and hand each controller a 4/4 flyer in exchange. That symmetry reads like a wash, which is exactly the misread the card invites. The reward scales with the wreckage, but the wreckage is something you choose, target by target. Aim it at your own board of one-toughness tokens and you are buying a flock of Dragons at the price of fodder; aim it at an opponent's lone fatty and you trade their threat for one 4/4 that flies, then keep moving. The design lives in that asymmetry of who is holding the better creatures when the spell resolves. A wide board of small bodies converts into a Dragon swarm; a deck full of expensive, hard-to-replace creatures pays full retail to get back flying 4/4s. It is a board wipe whose blast radius and net value you set yourself, which makes the timing question (whose creatures, and how many, do I want to upgrade or downgrade right now?) the entire decision. The Dragon tokens arrive with no further text and no evasion beyond flying, no enters-the-battlefield value, no bonus keywords, which is what keeps the conversion from being strictly upside: you are turning a diverse, abilitied board into a uniform stack of French-vanilla attackers and handing your opponents the same deal.
