My fave gen 7 pokemon gets the worst gx card
Here is to hoping that the text was too blurry to translate correctly.
All of these cards are good, but:
A. Ninetales > Mimikyu > Gardevoir
The GX attack is fairly bad when most of the relevant Ultra Beasts are less than 200 HP, Nagandel GX being the tankiest one, and most decks post rotation can OHKO Ultra Beasts without using up the GX attack.
I think the significant part here, is that A.Ninetales deals spread damage.
You can soften up targets, pull up a healthy one, and take a free-KO.
Now your opponent is left with a bunch of weakened Pokemon, which makes this:
[...] you just give your opponent access to Beast Ring, and then Stakataka GX will proceed to take a free counter KO
a less appealing option, as after they KO you, you will likely be able to KO back; maintaining an advantage.
I would rather run Sylveon GX [...]
This is true, however, Sylveon-GX struggles more with closing out games.
It's attacks are very linear, which is why it's mainly used in stall decks, or for setting up something else.
[...] If I'm not mistaken, devo spray didn't get a reprint, so reusing the ability is not an option either.
Not sure why you're against Acerola in this deck.
You can use it while A.Ninetales is active, so I don't understand the gust argument.
I think Acerola is great here, and gives A.Ninetales a lot of potential.
Speaking of...
Mimikyu GX is actually servicable now.
It's a shame that most of its good partners are Stage 2s like Decidueye GX and Greninja GX
Mimikyu/A.Ninetales works.
One spread, will make Mimikyu deal 100 damage, 130 total.
Which KOs most non-GX.
I feel like the consistency of A.Ninetales is being overlooked a bit.
Especially going into a meta with less draw supporters.
It doesn't even use DCE; 2 attachments of basic energy let it start attacking.
With Diantha, you can easily chain evolutions/attackers, and keep up a consistent threat.
This also allows you to go for a stalling route; since you can grab any items you want, and reuse them later.
