There's a reason Flash was banned/restricted in every format.
Griselbrand wouldn't work though (not a big deal). "If you choose not to pay, the creature is sacrificed immediately. No player will get priority in between the creature entering the battlefield and being sacrificed. Sacrificing the creature this way will trigger any abilities that trigger when it leaves the battlefield, and those abilities will be put onto the stack at the same time as those that triggered when it entered the battlefield."
I'm such a fan of your cube, going through the list/content every single day. So much cool/broken interactions! Love it!

Finishing the Horizon land cycle? Shard Triomes? Enemy Mirage fetches? Blue Wall of Omens? A catch-all enabling artifact that works in multiple combo decks? An Impact Tremors on legs? A Goblin Bombardment on legs? Magus of the Bond (Green Fastbond creature). Another Zuran Orb kind of effect?
I don't know. I could design dozens and dozens of cards I'd like to see.
