Recently, I achieved Level 60 in Pokémon TCG Pocket. I now have 85 emblems and 75 profile icons with B3 recently dropping. I try to aim to complete every mission and get 2 copies of every 1 ♦️, 2 ♦️, 3 ♦️ and 4 ♦️, and even 1 ⭐ where possible. I usually both copies of 1 ♦️ and 2 ♦️ midway through the month and 4 ♦️ by the end. I am currently trying to catch up with my missing 3 ♦️ cards as well as my Holofoils. These are the 50 ♦️ (all 3 ♦️) cards except Holofoils I still need second copies of from before B3:
