Mythrax the Unraveler does not seem to be scaling properly - I have: mech, murloc, undead/quilboar, and a Nightmare Amalgam, so I should be getting 5x 2+/2+ per turn, right? Nope, only getting 4x 2+/2+… not sure why…
Each minion can only be counted as one type. Otherwise, you’d get max value of just one Amalgam (since it counts as all types). Basically, Mytrhax goes down the list of minions, adding a type he hasn’t found yet and then moves on.
And more generaly
Dual type minions/amalgams only count for 1 in any multi-tribe synergy
2 notes :
amalgams are also counted for hidden tribes that no minion has in hs/bg (human, elf, dwarf…). Very niche but can sometimes have some impact
If you have a murloc and a dragon/murloc, and play a card that read “do something to a dragon and a murloc”, the game will be smart and always affect both. The dragon/murloc will not get the murloc effect and waste the dragon effect with your remaning murloc unaffected
