Being a Colorless type does it no favors, as it hits nothing for weakness and is stopped cold by Necrozma-GX’s Light’s End ability. 180 HP is on par with all of the EX Pokemon that we already saw, but one might wish for higher HP. Being weak to Fighting is actually dangerous, with Buzzwole-GX and Lucario-GX seeing lots of usage as of late, so it might not take a hit from those two. As of now, it would take a Jet Punch backed with Beast Energy and Choice Band to OHKO Tauros-GX. My goodness, now it looks bleak in that matchup! The retreat cost of three is so unfitting for a Pokémon that is pretty fast in the video games, though it can be searched via Heavy Ball and gets a small boost via Heavy Boots, which increases max HP by 20 and said Pokemon can’t be confused. Pretty specialized, though it’s nice to see different effects working together.
So how do we use Tauros-GX? Well, it can fit into any deck. I did hear about being paired with Ninja Boy, something to swap a damaged Basic EX/GX Pokemon with this Pokémon and blast them with either Rage or Mad Bull. Also, since it has no abilities, it can pair very nicely with Garbodor, whose Garbotoxin shuts down all abilities as long as it has a tool attached to it. And you can add in several disruptive cards to give your opponent’s even more grief on top of ability-lock. At least that what it was being used for back then. It could be used just like that now, except that I haven’t heard much about Tauros-GX in 2018, probably because it isn’t the main focus of a deck. There were decks with Tauros in 2017, but only two of those decks. And they’re both accompanied with Garbodor. Even though I haven’t seen any as of mid 2018, I’m not ready to count it out just yet.
In Limited, if you pulled one, then definitely use it. Double Colorless Energy is in the set, so you can easily attack with just one attachment. However, I cannot bring myself to give it a five out of five for Limited anymore because I could mislead people into thinking that such a card is unbeatable when it’s not. Horn Attack may get an early KO, Rage could be the second or third KO, and Mad Bull can be saved as a finisher.
Standard: 3/5
Expanded: 3/5
Limited: 4.75/5
Conclusion: Tauros-GX was a good card when it came out, but has been overwhelmed with other rivals that can actually hit repeatedly, rapidly, and reliably, without compromising too much. Still, don’t underestimate what Tauros-GX can do, as even one retaliatory KO on your only fully setup Pokemon can slow your momentum down, leaving you resourceless.
