Twice Upon a Time // Unlikely Meeting
Most Time Walk descendants pay for the free turn with an escalating cost, a heavy up-front investment, or a slice of your life total; this one gates the extra turn behind a board state instead. The casting restriction is absolute: without two or more Doctors under your control, the sorcery half cannot even be put on the stack, leaving it a dead draw in any deck that has not committed to the tribal engine and a game-ender in one that has. That single condition does all the load-bearing work, and it is what gives the Adventure half a reason to exist. Unlikely Meeting is not a throwaway rebate: it is the setup move that finds the second Doctor you need before the front face is legal to cast. Tutor for the pair early, assemble the board, then cast the extra-turn sorcery from exile for the turn that closes the game. Exiling the spell on resolution keeps the free turn one-shot rather than a repeatable loop, so the ceiling is a single explosive turn earned entirely through creature development. It is a rare Time Walk variant whose price is paid in commitment to a legendary creature type most extra-turn payoffs never touch, with a companion half built specifically to help you pay it.
