To win with Professor Putricide in Hearthstone Battlegrounds solo matches, save your three Hero Power charges for Tavern Tiers 4, 5, and 6. Spending 4 Gold on the Build-an-Undead ability early on low Tavern Tiers wastes limited charges on low-stat minions that do not scale into the late game. Activating the power on higher tiers unlocks powerful Deathrattle spawns, Reborn combinations, and Venomous tech minions that stabilize your board and carry your endgame.
Build-an-Undead Mechanics and Limits
Professor Putricide’s Hero Power, Build-an-Undead, costs 4 Gold and can only be used three times per match. Once all three charges are spent, the Hero Power cannot be used again.
When activated, you craft a custom Undead minion through a two-step drafting process:
- The first choice provides the base minion body, determining its starting Attack, Health, and any inherent keywords (such as Reborn or Taunt).
- The second choice attaches a secondary combat effect, such as an additional Deathrattle summon, stat buff, or combat trigger.
The minion choices offered in both drafting steps are restricted by your current Tavern Tier. Using charges while on Tavern Tier 2 or Tier 3 limits your selection to low-tier bodies with minimal scaling. Waiting until higher Tavern Tiers adds high-impact combat effects, token generators, and utility mechanics to the drafting pool.
When to Use Hero Power Charges
Because 4 Gold represents a major portion of a turn's budget, plan your three crafting activations around critical leveling breakpoints.
| Tavern Tier | Recommended Usage | Strategic Focus |
|---|---|---|
| Tier 1–2 | Do not craft | Focus gold on leveling and purchasing shop minions for early board strength. |
| Tier 3 | Emergency only | Craft once only if facing imminent elimination to prevent fatal combat damage. |
| Tier 4 | First charge | Craft a stabilizing mid-game unit with Reborn or multi-token Deathrattles. |
| Tier 5 | Second charge | Hunt for high-tier stat buffers, scaling enablers, or heavy token spawners. |
| Tier 6 | Final charge | Create an endgame tech piece, Venomous removal minion, or mass summoner. |
In a standard game, use your first charge on Tavern Tier 4. Mid-game shop rolls often fail to match boards fielded by high-rolling opponents; crafting a Tier 4 custom Undead provides immediate tempo and protects your Health while you save gold to level to Tier 5. Use your remaining two charges across Tiers 5 and 6 to build your final composition.
Undead Crafting Selection Priorities
When drafting your custom Undead, prioritize utility keywords and persistent combat presence over flat base stats:
- Inherent Reborn bodies: In the first pick, look for minions that naturally feature Reborn. Choosing a Reborn base allows you to attach a Deathrattle in the second pick, effectively triggering that Deathrattle twice during combat.
- Token-spawning Deathrattles: In the second pick, select Deathrattles that summon multiple Undead tokens. These synergize with attack-scaling engines and absorb enemy hits.
- Venomous tech: If offered, select Venomous effects to bypass opponents reliant on single, high-stat minions.
- Combat stat buffs: Look for abilities that grant combat-wide attack bonuses to your Undead, increasing the threat of every token spawned.
Board Positioning for Custom Undead
Custom Undead frequently combine Reborn and Deathrattle spawns, which makes board space management critical. If seven friendly minions occupy your board when a unit dies, any additional Deathrattle tokens will fail to spawn.
- Frontline (Slots 1–2): Place non-spawning attackers or shield-popping units here to trade first and open board space.
- Mid-board (Slots 3–4): Position custom creations that have both Reborn and Deathrattle summons in the middle of your attack order. This timing ensures earlier friendly units have died, leaving empty board slots for both the Reborn body and its spawned tokens to appear.
- Backline (Slots 5–7): Place passive stat-scaling engines and fragile buffers in the back so they survive long enough to buff every wave of combat summons.
Playing the Late Game Without a Hero Power
After spending your third charge, Professor Putricide has no remaining Hero Power. Do not force a mono-Undead board if the tavern stops offering complementary support units. High-tier custom Undead with Venomous or heavy Deathrattle summons function effectively as standalone anchors in mixed compositions. Shift your remaining gold into standard tavern upgrades, looking for utility minions such as Divine Shield removal, cleave attackers, or neutral tech units to counter specific opponent setups.
