Hearthstone Game Designer on Battlegrounds, Dominic Calkosz, has tweeted some clarifications on how the stat reductions from Vol'jin and Xyrella will effect golden minions - triples. But first, here are those new heroes just in case you aren't familiar with them.

 

And here's how those pesky stats are going to work out when it comes buffs and debuffs.

  • A golden minion will always have at least base stats.
    • If your golden minion is a 6/6, when it is created through a triple, it will be at least a 6/6.
  • All buffs and debuffs carry over on top of the base golden stats.
    • If you have a -2/-2 debuff on one minion, and a +7/+7 buff on another, this gives your golden +5/+5 stats.

Read on for the full details on how it works including some examples from Dominic.

Quote From Dominic Calkosz

With Vol'jin and Xyrella coming to Battlegrounds, you can now *reduce* the stats of minions. So let's talk about how that affects triples.

TL;DR: All +/- stats carry over, BUT you'll get at least base Golden stats.

In other words, the added/lost Attack on each minion will transfer to the Golden, but if the net change is negative, it will be ignored instead. (Same for Health.)

If a 1/3 minion has stats set to 2/2 by Xyrella or Vol'jin, that is considered +1/-1 for tripling.

Here's an example. If you have three Freedealing Gamblers (base 3/3) all reduced to 1/1, you still get a 6/6 Golden.

But what if you have reduced stats on one minion and buffs on another? The buff will be reduced. Here you have -2/-2 and +7/+7, which comes out to +5/+5.

Last example. If Attack is reduced below base Golden stats, but Health is increased, then you'll still get the bonus Health without losing any Attack.
