If I use Gideon’s 3rd power on a creature, and then cast his 1st power on that same creature, what will be the resulting regeneration:
a) 5 (regen doesn’t stack)
b) 6 (regen does stack)
c) 1 (regen overwrites)
Answer: D - Only the highest value applied takes effect. In other words, Regenerate 5 will override Regenerate 1 - but not the other way around.
How is this not A?
Yes, it’s A. Regen doesn’t stack, just takes the greatest. Too bad tho 
Thanks! Good to know!
