@dragonlordged: There is a special rule in place just to deal with this type of scenario. No replacement effect can replace the same effect more than once. This is why effects that double damage are not infinite, but having multiple Furnaces of Rath works.
I think that Krark's Thumb replaces one flip with two flips, and then the second Thumb would replace each of those with two more flips, but the same flip effect would never be replaced twice by one Thumb. So the net effect of having two copies of Krark's Thumb in play should be that you flip four coins and ignore all but one.
Reference:
614.5. A replacement effect doesn’t invoke itself repeatedly; it gets only one opportunity to affect an event or any modified events that may replace it.

Using Krark's thumb is a snap! No Twiddle required - just use the best coin-flip cards you can get and thumb your nose at the odds! Shooting for three with Fiery Gambit can really nail an unsuspecting opponent, quickly reducing him to single digits. A fiery assault like that will force even the most stalwart opponent to knuckle under! Add in Goblin Bookie to up your odds and you can really launch a joint offensive.
Help me... I can't stop.

R&D claim this card is legendary solely to minimize how often they'd have to explain what happens if you have two of them.

Maybe it's not that powerful - or at least, needs unpowerful cards alongside it to work - but who cares? It's fun and funny.

It's a must for decks relying on coin flips, obviously. However, there may not be too many mainstream Chance Encounter decks running around... but still, it's cool! :D

This card would be a lot cooler if it wasn't legendary, as then it would at least give you the possibility of making coin flips fairly consistant. As-is, it is too inconsistent.
Maybe someday they'll make a creature which does this.

Well, Ral Zarek is coming out in Dragon's Maze. I wonder if people will start dusting off the Thumb. I can almost see this making a splash in Modern with Mr. Zarek.
Almost.
Nah.

I love this card and it is loads of fun, however.
I don’t think Mirror Gallery will help this card as much as everyone seems to think it does.
The card reads (if you didn’t read it above) “if you would flip a coin, instead flip two coins and IGNORE ONE.” Not “Pick any number of winning coins from the pile you just flipped” For every pair of coins you get one mandatory outcome. So with 2 out you would flip 2 coins twice and get 2 outcomes that may not work with eachother. Such as Goblin Archeologyst, you win, destroy target artifact, you lose, sacrifice the goblin. You can’t sacrifice the goblin more than once. So if you have all 4 thumbs out, (16 coin flips) it will happen.
-Chance Encounter works well enough, loosing flips dosen’t remove counters so you could be adding as many as 8 counters per coin flipping event.
-Wirefly Hive wont work, one of your 8 pairs of coins WILL kill all the wireflys
-Goblin Bomb is just as likely to remove 8 counters as add 8 counters, so having 4... (see all)

this is a very fun card to play with
however alot of you are suggesting using mirror gallery with it to further improve your chances. however, i recently asked a judge some questions about replacements effects for a few other combo's i was working on, and he told me that replacement effects do not stack. i forget exactly who it is that chooses(i think maybe active player) but in any case only one is chosen to take effect, the rest are essentially ignored. krarks thumb says 'instead' meaning that it is a replcement effect and thus multiple krark's thumbs are redundant.

In response to Yotiansoldier:
You are correct in your evaluation of the coin-flip-expansion (Doubling for every Krark's Thumb in play) But you need to remember, each individual coin flip isn't a win/lose instance, it's simply heads or tails.
Example: You have two thumbs in play, and you play Stitch in Time, calling heads as your winning toss.
Here's how it breaks down:
1-The first thumb will replace the initial coin flip with two coins instead. (A and B)
2-The second thumb will replace coins A and B with two of its own each. (Creating coins a, b, c, d)
3-You flip all four coins:
a-is tails
b-is tails
c-is Tails
d-is heads
4-a-Coins a(tails) and b(tails) were a result of coin A being flipped, so you ignore coin a and get tails as your result for coin A.
b-Coins c(tails) and d(heads) were a result of coin B being flipped, so you ignore coin c and get heads as your result for coin B.
5-Coins A and B were a resu... (see all)
