When Welder is used to attach 2 Fire energy, does Old Cemetery trigger once or twice?
Any energies attached from the hand would trigger Old Cemetery, once for each energy card being attached. So in this case you would put 4 damage counters total.

If Kecleon has no Energy attached and I attach a Psychic Energy to it when Old Cemetery is in play, will Kecleon's "Chromashift" Ability kick in before checking for Old Cemetery or will Kecleon get 2 damage counters?
Old Cemetery's effect will happen first, so Kecleon will receive 2 damage counters.
