Thalisse, Reverent Medium

Most token doublers multiply the moment tokens hit the battlefield; this counts them instead, then settles up before the turn is over. That distinction is the whole engine. Where a doubler cares about a single trigger, Thalisse cares about the entire turn's ledger: every Treasure, every Clue, every soldier and saproling and squirrel you assembled between untap and cleanup gets tallied, and the delayed payout arrives as a flock of flying spirits when the turn winds down. Because the count is limited to tokens you created, the effect keys off your own production, which means the way to feed it is to front-load your generation before the tally happens. Watching every end step rather than only your own still matters: if you can make tokens at instant speed during another player's turn, Thalisse counts those too and hands you spirits well outside your own turn. The design is a counter rather than a replacement effect, so it stacks with actual doublers without redundancy: double your production during the turn, then Thalisse counts the doubled total and gives you that many spirits on top. The 3/4 body closes nothing on its own, and because the payout keys off tokens made earlier in the same turn, the spirits always trail the work rather than compounding within it. It rewards going wide rather than tall, but its count-everything rhythm, tallied once per turn and paid out as the turn ends, is unlike anything the enter-the-battlefield doublers offer.
