Um... I don't believe multiple Krark's Thumbs would stack.

there was an article on the site that got pretty in depth about multiple thumbs, so i hope it works.

Q: How do multiple Krark's Thumbs interact with Mirror Gallery? --Jeremy S.

A: Mostly the Thumbs cling to the Gallery saying, "please don't leave us!" because then the state-based effects boogieman would send the Thumbs to the graveyard.
Let's say for a minute you're asking about how multiple Thumbs interact with each other. Here's a handy chart:
1 Thumb = 2 flips
2 Thumbs = 4 flips
3 Thumbs = 8 flips
4 Thumbs = 16 flips
5 Thumbs = 32 flips...
Yes, I wrote "5 Thumbs"-- Sculpting Steel, Copy Artifact, and a host of other ways can give you a hand at having way too many Thumbs.

I think this is an instance of Wizards breaking their own rules. It should not work. But apparently because they thought it would be funny, it does.
