Ran and Shaw

The enters trigger is where the whole build-around lives, and it locks two doors at once. It wants three or more Dragon and/or Lesson cards already sitting in your graveyard, which reads as a card written for a deck that treats its yard as inventory rather than overflow. It also insists on a hard cast: the copy appears only if you cast the creature, so reanimation, flicker, and blink loops all miss the reward. That "if you cast them" clause rules out the obvious cheat of dropping a 4/4 flier into play and duplicating it for free, and it forces you to earn the token through the graveyard count itself. Firebending 2 is a separate lever pointed at the same target, adding to the aggression the keyword rewards. The payoff is another 4/4 flier carrying the same anthem, and since that pump has no tap cost, a lone Ran and Shaw can fire it repeatedly with the mana to spare; the token's real value is a second body to receive the buff and a second attacker in the air. In isolation this reads as a plain five-drop. Once a Dragons-and-Lessons shell has done its stocking, it becomes a doubling threat that a single removal spell no longer fully answers.
