The two best cards from Homelands are spells anyhow (Merchant Scroll and Memory Lapse), further adding insult to injury

It is also a corner of the pin stab Roman card
Here are all the cards you need for 'Celestial Guardian's Museum 1': Tsareena #158 (Full Art / One Gold Star) Tapu Bulu #159 (Full Art / One Gold Star) Oricorio #165 (Full Art / One Gold Star) Tapu Koko #166 (Full Art / One Gold Star) Cutiefly #167 (Full Art / One Gold Star) Comfey #168 (Full Art / One Gold Star) Sandygast #169 (Full Art / One Gold Star) Rockruff #172 (Full Art / One Gold Star) Mudsdale #173 (Full Art / One Gold Star) Magearna #175 (Full Art / One Gold Star) Drampa #176 (Full Art / One Gold Star) Komala #179 (Full Art / One Gold Star) Rewards: 12 Pack Hourglasses, 36 Pack Wonder Hourglasses and 10 Shop Tickets
I definitely prioritized the second copy of Sabu, which greatly speeds you towards the pendulum dreamstate
