Hey Mark, unrules interaction question. If I conbtrol both Krark's Other Thumb and Pixie Guide, and then cast Hydradoodle or Neverwinter Hydra for 3GG, do I roll three instances of 2d6 (ignoring the lowest roll each time) and then roll another 2d6 ignoring the lowest roll for pixie guide, or would I roll three instances of 3d6 and ignore the lowest two dice for each instance?

First, I’ll assume you mean you paid the right amount of mana to roll three dice (6GG not 3GG). Here’s what happens. Instead of rolling three dice, you roll four because of Pixie Guide. Then you’re going to roll one die at a time, but for each of those four rolls, you roll an additional die along with it because of Krark’s Other Thumb. For each of your four die rolling actions, you’ll pick one of the two dice to count as your roll. Once you have four chosen results, you then pick three of those to count for the Hydra roll. Here it is spelled out:Roll #1 - roll two dice and pick a result.Roll #2 - roll two dice and pick a result.Roll #3 - roll two dice and pick a result.Roll #4 - roll two dice and pick a result.Than chose three dice from the four rolls.Those three die rolls are for the Hydra.

Un-rules question. If i cast More or Less on Pixie Guide, and change its effect to "roll that many dice plus two and ignore the lowest roll." how dies that interact with d20 cards from AFR, like Contact Other Plane? do i add the two d20 rolls together, or do i pick a die to use for the effect?

You ignore all but the highest roll.
