When Extinction Blast discards three cards, do Unending Energy's triggers wait until all three discards are done?

Question

Accepted Answer

Probably. The three discards are one cost paid at once, before other effects trigger, so Cyclops returns only after the cost is paid. Only one reply addresses this, so treat it as a best reading.
