You can easily draw an extra card every turn with this card's effect if you also have "Karakuri Shogun mdl 00 "Burei"" on the field. Manually change a face-up Karakuri monster's battle position, then using "Burei's" effect to change it again so it'll stay in the position you want it in.
If you're running a pure Machine-type Karakuri Deck and you wish to use "Solidarity", you can use "Unknown Synchron" alongside Machina Fortress instead of Plant-type Tuners. Special Summon the Synchron, then Special Summon Fortress and tune for this card.
Since Unknown Synchron can be searched with "Tuning", you could also tech cards like "Quickdraw Synchron" to build a different Karakuri variant.
Combine this card with "Zero Gravity". Using it on your opponent's Battle Phase will stop their big attackers and switch your monsters' positions, allowing you to draw a card to replace your Trap and stop incoming attacks.
Synchro Summon this card, then activate "Stumbling". Every time you Normal Summon a Karakuri monster, it will go to Defense position, allowing you to draw 1 card. Since Stumbling also affects your opponent's monsters, is unlikely he/she will be able to launch a successful attack to destroy your monsters.
