How many Zekrom, Reshian, and Kyerum do we catch?

Hey fam,

I am a little confused with how the event helps, so if someone can simplify, I’ll be grateful.

Reshian fuses with Zekrom, and Kyerum, so we want 3 min. 2 to fuse, and 1 to level.

Zekrom and Kyerum, I believe we get fusion energy from them and will need to catch 10 ish?

Edit: can anyone confirm if we can receive fusion energy from remote raids, and that energy is received from fighting white/black Kyerum?

Edit 2: From fusion, the stats taken is from Kyerum, and not Zekrom/Reshian?

Thank you in advance!
