Alice in her Puppet Maker form serves as a beneficial addition to the Puppet axis.
Although it's not as exaggerated as Spiritual Embracer Alice's enhancement to the Spiritual Energy axis, it's still not weak.
Puppet followers have many hand traps and graveyard traps, so it's easy to enter the exile zone due to their effects, and Shen Sui indeed needs a way to recover Puppet cards from the exile zone.
Because the nature of a Life Card Duel allows for infinite liberation, the Puppet follower cards recovered to the hand don't necessarily need to be discarded by a Spell Card effect to be sent to the graveyard. Shen Sui can also normal summon them and then liberate them to send the Puppet follower cards to the graveyard.
