x2Severe PoisonYour opponent's Active Pokémon is now Poisoned. Put 8 damage counters instead of 1 on that Pokémon between turns.
Poison AbsorptionIf your opponent's Active Pokémon is Poisoned, heal 100 damage from this Pokémon.
[-][+] Nasty Goo Mix-GX: Your opponent's Active Pokémon is now Paralyzed and Poisoned. If this Pokémon has at least 4 extra Energy attached to it (in addition to this attack's cost), put 15 damage counters instead of 1 on that Pokémon between turns. (You can't use more than 1 GX attack in a game.)
If I had used Muk & Alolan Muk GX's "Severe Poison" attack that places extra Poison damage counters and in the next turn use Koga's Trap, do they still place the extra Poison damage?
No, they don't. The new, normal Poison Special Condition replaces the old Severe Poison Special Condition.
If I Switch my Active Pokemon that is affected by Poison from Muk & Alolan Muk GX's "Severe Poison" attack and Dust Island is in play, does my new Active Pokemon take the extra damage counters?
Yes, it does. Dust Island specifies that it is affected by "that Special Condition".
