Yes I have seen them! I check Pokebeach.com daily, so I see most leaks that happen, but I guess that makes me a bad TCG blogger for not making posts about them >///<. Bearing in mind that the translations we have aren’t 100% confirmed (but Pokebeach.com is usually pretty good with their translations) [M Tyranitar-EX] does look formidable, and it can get the energy it needs in one turn with a DCE and 2 Mega Turbo, don’t forget that it has Theta Double too, which means that after you put a Spirit Link on it to evolve it, you can then put on an additional tool ([Muscle Band] would be a bit redundant, but I can see using [Hard Charm] or maybe even [Weakness Policy] if Fighting decks kick off). People are excited about playing this alongside [Golbat PHF 32] and [Crobat PHF 33]. This deck will most likely make an impact on the competitive Meta.
The other two I’m not so impressed with. Firstly, I don’t quite get [M Ampharos-EX]. To do 170 plus Paralysis it takes four energy and then it does 30 damage to itself. Granted, it gets set up just as fast as M Tyranitar, but it just looks so sloppy. Also it doesn’t have the same longevity in a game that Tyranitar or another Mega would have since it helps your opponent KO-ing it.
The thing is, we want our Megas to do a ton of damage—that’s why we put in the work to get them out and powered up. 170 damage truly isn’t something to laugh at, but we’ve got [M Rayquaza-EX ROS 76] doing 240 damage; [Primal Groudon-EX PRC 86] doing 200+ damage with lots of support from Muscle Band, [Strong Energy], and [Fighting Stadium]; M Tyranitar-EX is doing 230 damage after one Golbat hits the field. For a Mega not to be doing amounts of damage of this magnitude, it has to have a stupidly good effect or some other benefit. For example, [M Kangaskhan-EX FLF 79] used [Aromatisse XY 93] by moving the energy off of it so you could heal with [Max Potion] (it was also the best Mega at the height of its popularity). [M Manectric-EX PHF 24] was good for its energy acceleration (to power up your next Mega Manectric) and also plain old [Manectric-EX PHF 23] turned out to be a great attacker on its own.
[M Sceptile-EX] I’m really on the fence about. I think it suffers the same problem as Ampharos, that its damage output is just too low. The attack effect on paper does look “stupidly good” but let’s dissect it just a little bit. The current translation says that you may attach up to two energy from your hand to your benched Pokemon. So to get off a Jagged Saber to accelerate two energy, you need two energy in your hand when you attack. That’s the deal-breaker for me, the consistency of that attack seems a bit too low for me. But I could be wrong, and I’m certain there will be a lot of players wanting to play an M Sceptile-EX deck, and from that, eventually someone will come along with a really good decklist.
Now let’s consider an alternative. What about [Sceptile PRC 8]? Now, this is a bench-sitter whose ability does half of what Jagged Saber does (granted, without the damage) but the consistency is somewhat increased. We can play an extra Grass Energy (healing 30 when we do) but this can be to our Active Pokemon if we wanted. Again, it has to be from your hand, but this time we aren’t pressured to have the energy in-hand for an attack, but rather we can put down Grass Energy as we draw into it.
Thanks for the ask! Happy Battling!
