We all know that during the Standby Phase when Drill Warrior special summon himself and adds a Monster from the Graveyard back to the hand, you cannot chain Bottomless Traphole.

What if there's no Monster in the graveyard? Can Bottomless Traphole be chained to the Special Summon of Drill Warrior during the Standby Phase?

Yes it will be destroyed and removed from game since the last thing to happen is the special summoning and not the taking back of monster.

Ok thank you.
