Rerolling in Illusion Connect is very easy due to it having a guest account option.
You can just create an unlimited amount of them until you get the best units, then bind the account.

Best Units
SSR Units
Miyuki
Top tier unit, one of the best in the game. She should be your top pick.
Anna
Best healer in the game.
Kiraya
Best early game tank and easy to obtain due to being on the Miyuki banner.
Nicola
Amazing endgame unit, but not so great early on and at 3*
Maki
A great unit, and the only one that can currently be awakened. If you’re going to spend a lot to awaken her, having an extra copy can help.
Yuffie
Great AOE unit, especially at 5*. Good at early game, but not a super priority to get her.
SR Units
Pan
One of the best SR units due to being a counter to healers such as Anna.
Rikia
Solid SR unit with dispels and debuffs in her kit.
