Standard Gengar/Trevenant BREAK or Gengar/ Alakazam EX

[Lord Goomy]

Yup.
Creep Show Gengar. There's one from Generations and one from Breakthrough that do the exact same thing.
Here's the list:
Pokémon: 19
4 Gastly (CRI)
2 Haunter (CRI)
3 Gengar (BKP)
1 Gengar (CRI) (Crimson Invasion)
3 Phantump
3 Trevenant
3 Trevenant BREAK

Trainers: 30
4 Ultra Ball
4 Rare Candy
3 Wishful Baton
2 Field Blower
2 Evosoda
2 Rescue Stretcher
1 Super Rod
2 Random Reciever
4 Sycamore
3 Shauna
3 Altar of the Moone

Energy: 11
2 Counter Energy (from Crimson Invasion)
9 Psychic Energy

Set up with Trevenant BREAK, and insta-OHKO with Gengar.
There is a possibility of replacing the Trevenant BREAK line with Alakazam EX, which does remove clunkiness and get space, but at the sacrifice of lower reliability (only targets Pokémon with energy attached.)
If I was to make the switch to Alakazam EX, the list would look somewhat like this:
Pokémon: 13
4 Gastly (CRI)
2 Haunter (CRI)
3 Gengar (BKP)
1 Gengar (CRI)
3 Alakazam EX

Trainers: 34
4 Ultra Ball
4 Rare Candy
3 Wishful Baton
2 Field Blower
2 Evosoda
2 Rescue Stretcher
1 Super Rod
2 Random Reciever
3 Timer Ball
4 Sycamore
4 Shauna
3 Altar of the Moone

Energy: 12
2 Counter Energy
10 Psychic Energy

So. Any help would be a help, and one question needs to be answered ASAP:
Alakazam EX or Trevenant BREAK?
Alright. Let's get started.

Honestly, it seems a bit excessive to run Tevenant BREAK when Tapu Koko Promo exists. There's also Weavile, though it only hits pokemon with abilities. If you want to run a 'tier 3' Pokemon I'd say Decidueye Gx would be best; running two Stage 2 lines is still unreliable at times but at least you'd be increasing the usage of your Rare Candies...

In regards to Alakazam Ex, I actually opened this because I was expecting to see Mega Alakazam Ex in the deck; not sure how well it plays but it's something I've been interested in trying out. Similar to Decidueye GX, clearly, but operates on different principles.
