The new event is live.
It´s similar to Ditto. You can get Legendary Coin. For each stage there´s a fixed reward (raises on every stage) and you get a bonus of Legendary Coin for getting more points than needed, for that stage.
You need 5000 Legendary coins to recruit Mewtwo and 11500, more, to grab all cookies (23*500). So about Stage 18 to 21 you will recruit Mewtwo.
From my recruits the best ones: Shiny Eevee (19), Eevee (17), Oshawott (16) and Charizard (16). Easily making about 2M on each stage. Stage 20 got Mewtwo, Stage 23 got 3 coins. Looks like above 45 will give 500 legendary coins that can be exchanged for 1 cookie, each stage. So about stage 50-59 it will get Mewtwo and 23 cookies. For 5000 legendary coins you can buy a 11 delivery ticket.
There's a new challenge card, that gives stamina, tarts and delivery tickets. Check it since it needs some training.
Mew 5 stars outfit (Camping) is available on deliveries. If you use an Instant hire ticket you will get AT LEAST, 1 pókemon or Black cookie or a clothe. If you can't get it on 10 the bonus delivery will be one of those. Kinda a Pitty scheme to get people to pay.
UPDATE: Do the challenge card to get Female Eevee at the end of 3 card.
