For Sarkhan's ult, dragons that entered the battlefield and have haste (either with flameshadow conjuring or reckless bushwhacker) don't do the 4x damage when they attack. It seems they should deal the 4x damage based on the wording of text in Sarkhan's third ability.
Lashweed Lurker was nerfed ina recent patch so that it can't target tokens anymore.
But Gone Missing should still work on tokens. I'm quite sure I killed a moon token with that...
