Assuming you're referring to the game Hearthstone, side decking is not a mechanic in the game. However, I can provide some general tips for countering an Undead Priest deck.

Undead Priest decks often rely on controlling the board with minions that have Deathrattle effects, and then resurrecting those minions for additional value. To counter this strategy, you can include cards in your deck that either silence enemy minions or destroy them outright, such as Silence or Shadow Word: Death.

You can also try to overwhelm the Priest with aggressive minions and spells, forcing them to use their removal spells and board clears inefficiently. Cards like Blessing of Kings or Truesilver Champion can provide a strong early game board presence and keep the pressure on the Priest.

Finally, you can try to disrupt the Priest's resurrection strategy by milling their cards or using cards that remove cards from their deck, such as Coldlight Oracle or Gnomeferatu. This can limit the Priest's ability to draw the cards they need to execute their game plan.

Keep in mind that every deck and player is different, and your strategy will depend on your own deck and playstyle as well as the specific cards and strategies employed by the Priest.
