MTG Salvation

Can creatures put into play by Ilharg, the Raze-Boar be kept into play using sundial of the infinite at the beginning of your end-step?

You can activate Sundial during your end step while the delayed triggered ability from Ilharg is on the stack. If you do, that ability will be removed from the stack as part of ending the turn, and it won’t trigger again, effectively letting you keep the creature you cheated in indefinitely.
