Gravekepper's Chief, Jaden and others in “Unfinished Business”

Gravekeeper's Spear Soldier! [summons Gravekeeper's Spear Soldier in attack position] I hope your Bubbleman's draw provided you with two very good cards, because already, he's outmatched in battle, and he is soon to be outnumbered as well!

Uh-oh.

I now summon in attack mode, Gravekeeper's Guard! And his effect lets me return a monster that's out to its owner's hand. And the monster I choose, is Bubbleman!
