In the scenario with the Etali, planar disruption and eldest reborn, the order you cast doesn't them doesn't really matter. No matter what you do your opponent knows which creature the planar disruption is targeting so they can sac it to eldest reborn, even if the planae disruption hasn't resolved yet.
Man that 4th game was so good. I thought for sure you were done for lol. I couldn't figure out WHY he left the game until you said he milled himself lol. That suuuuucks for him but congrats for you!!
