Yes. A lot of decks are running Patches.
You can’t go wrong with that.

Ice Block keeps your cocktails cool… and they provide an instant activation for Medivh’s Valets (MV) battlecries.
If you have no MV’s in your deck I would suggest to replace it with a Potion of Polymorph.

BTW if you lack the MV’s why not replace them with Kabal Lacky? They have more synergy with this deck.

However I would strongly suggest to craft the MV’s.
