Attempted to update some examples on IPG 2.1 Game Play Error — Missed Trigger - Rules Resources
For a Triggered Ability that causes a change in the visible state, I changed some cards I used : [Aurelia, the Law Above] [Anointer Priest][Mole Man, Moloid Master]
originally I updated all three to cards from the marvel set, but none of them showed.
I tried other cards with older sets, and kept trying and trying. SoS, EoE. Finally I was able to get cards from Karlov manner to work.
Dunno why,
but the current page with the 3 examples above are 2 working, one not working.
