Hearthstone BattlegroundsSeason 3 has introduced a new minion type to the battlefield: Undead. With these new minions comes an entirely new way to play the game. Undead cards rely on a lot ofReborn synergyand some powerful late-game cards that can go toe-to-toe with some of the existing best endgame builds in the game.

This guide covers some of the best Undead builds and cards that you can use to win games, including when to pick up cards, good strategies for discovering minions from the tier above, and the sort of perfect boards you need to aim for to win.
Updated Jun 29, 2025:We’ve updated this article to include a video guide that shows you the best Undead builds for Hearthstone Battlegrounds.
Eternal Knight Build
The absolute perfect set-up for a powerful Eternal Knight build is to pick these up early (they appear on tavern tier two) and then level quickly to be in chance of grabbing at leastone of the seven available Eternal Summoners.These tier six minions are probably one of the best in the game now - they can be very, very strong even if you haven’t been scaling those Eternal Knights from earlier in the game.
The ideal board set up is preferably some buffedRisen Ridersto act as Taunts as they protect yourSummonersso that they can get full value (maximum spawns of Eternal Knights), as well asSoulsplittersto give yourSummonersreborn. With more reborns come more Eternal Knights.
Sister Deathwhisper Build
The Sister Deathwhisper build is very strong, but it really relies onhaving Reborn minions ready to goand aboard of Undead.Minions like Soulsplitter and Handless Forsaken provide fantastic synergy, but even a buffed Deathrunner Blanchy will fit nicely into this build.
It is strong enough that you’re able to pivot to a full Undead build once you pick it up, but if the lobby is stacked with other players who have already picked Undead,you might be in a bit of trouble.
Mid-Range Ghoul Of The Feast Build
Ghoul Of The Feast is a card we didn’t predict to be particularly good, but when used correctly, it can provide amassive tempo swing.Tempo is basically a way of describing when you get a quick (usually temporary) advantage over other players in the game. This can allow you to level up quickly and grab build-defining cards from the higher tavern tiers.
Much like other Undead cards, this does require a bit of synergy - you need to have some units that provideAvengetriggers, but also enough minion types to make this actually worthwhile. Mechs and Beasts work very well with this card, alongside Reborn undead.

Early Hungering Abomination Build
While we didn’t originally have Hungering Abomination rated that highly, we think that this is aperfectly reasonable card to structure a top four build around. There is a bit of set-up involved with making this card work though: it needs to be acquired early, and you need to have at least someAvengesynergy ready to go. This doesn’t necessarily meanRebornUndead - it could mean Mechs with Menace or Beasts with Rats.
You also shouldn’tsolely relyon the Hungering Abomination, but it can be a good way to get some very high stats on a single unit to allow pivots into other late-game builds. It can fit into alate-game Reborn Undead buildalongside powerful units like Sister Deathwhisper.
Sin’dorei Straight Shot is thenumber onecounter to Undead Reborn builds, mostly because a lot of theRebornsalso have Taunt. Sin’Dorei removes both Taunt and Reborn, which can cripple some of these builds.
Big cleaves, especially theElemental Wildfirewith a stacked Elemental build can also wreak havoc on builds that rely on multiple reborns. Mega Windfury Elementals are also quite strong at taking out minions that are buffing mid-battle.
