The GO wild area event will be on 15th and 16th November and will give access to the Safari balls (ticket holders get more of them, probably very few for F2P). They are said to have an even better catch rate than Ultra balls. These will be ideal to catch Galarian Birds. Having longer daily adventure incense will be beneficial.
Note: Encounter with Galarian Birds is not guaranteed.
To reach tier 50, you'll need 5000 points.
The daily task of catching 15 pokemons gives 200 points/day. (200*11= 2200)
Weekly tasks give a total of 1000 points/week. (1000*2= 2000)
You'll need just 800 points more. That can be gained by catching pokemons(5 points each), hatching eggs(40 points each), or raiding(100points each). Daily limit of 250.
It is easily doable.
