Krark's Other Thumb and Clam-I-Am interraction.

**Edit. Tested again and now both are applying but Clam-I-Am applies first.**

I don't know why my first test seemed to have different results. Original message left below. But not so bad now - but does still appear to be in the wrong order.

I have done more testing and it appears Krark's Other Thumb doesn't give a popup to choose if both rolls are the same. Also, if both rolls are 3s, Clam-I-Am gives two prompts to reroll them. So it appears Clam-I-Am is giving the chance to reroll each of Krark's Other Thumb's two die.

======================
With both Clam-I-Am and Krark's Other Thumb on the battlefield, it appears only one applies.

I will either be prompted with:
* reroll the 3 (obviously from Clam-I-Am triggering), or
* a choice of two rolls (obviously from Krark's Other Thumb).

My guess is that if a three is rolled, Clam-I-Am takes precedence, otherwise Krark's Other Thumb gets to play.

----------------------------------------------

I am not sure what the ruling should be but I would expect it to be one of the following. (I would expect (A)).

Option A
When you roll a die:
* Krark's Other Thumb rolls two die instead of one.
* After choosing the result, if a 3 is chosen, you get a reroll and again Krark's Other Thumb causes two instead of one.

For example: you roll a 5 and a 3, and choose 3.
You elect to reroll and roll a 2 and a 4, and choose 4.
Final result (4).

Option B
When you roll a die:
* Krark's Other Thumb rolls two die instead of one.
* If any three is rolled, Clam-I-Am triggers and allows a reroll of that value.
* Krark's Other Thumb turns that reroll into two rolls to choose between.

eg, you roll a 5 and a 3. Then reroll the 3 and get a 2 and a 4.
You select from 2 and 4, and choose 4.
Then you select from 5 and 4, and choose 5.
Final result (5).

Start by reproducing the interaction between Krark's Other Thumb and Clam-I-Am using the scenarios in the issue, then inspect the implementations of those cards and the roll-trigger handling. Confirm the intended Magic ruling before changing behavior; done means rerolls and choice prompts follow one agreed ordering without duplicate or missing prompts.
