Phyrexian Vindicator is an excellent back up plan therefore, as basically the only other card in your deck aside from Stuffy Doll that will make a good target for all those spells

EDHREC players, for example, run this pretty frequently in Tinybones, Trinket Thief, Tinybones, Bauble Burglar, and Tergrid, God of Fright, all commanders that excel leading decks that aim to whittle opponents down to zero resources as soon as possible
