So you can turn 1 cast Muxus off Tomb/City + Mox/SSG + Sticker Goblin + Muxus?

How consistently does Turbo Muxus happen? You have redundancy for the mana (8 copies of each), but still need the other 2 pieces in hand too. Does this happen often?

What was the reason to change to this plan over cheating Muxus with Lackey/WInstigator?
