i dont have them tho lucario is invincible and scep does 6o+ for 2 energys
3 energies. Sceptile EX's body increases it's own attack cost, since it's an EX.
*2 weakness to grass (a rising type with Leafeon LV.X) and *2 weakness to Fire (A decreasingly common type, but Magmortar is still pretty well spread) isn't ideal for a card that you want to use often, especially a stage 2 which'll take resources, and an EX, which'll cost 2 prizes for Leafeon to gladly snatch up.
~~~~~~~~~~~~~~~~~~
It appears you are a bit unfamiliar with energy lines, so... To help a bit with why the energies are problematic...
1) You don't even play any water pokemon, but are playing 1 water energy. Why not an energy type that can actually be used to pay costs besides colorless? Why not an energy that can provide multiple energies at once?
2) Mightyena EX looks like a card which could be useful, it's got a great power, resistance to Gardevoir... Except the 100 HP is a smidgeon too low to be active in a format where pokemon deal 70 or more damage on average. It has free retreat, meaning your energy is better placed onto a card that can deal more damage then 30 (not enough to KO Banette even) or the single dark energy requiring second attack. ...Which, suffers due to the lone dark energy being capable of being prized, and 90 damage to stage 2 pokemon leaves ALL of them 10 HP or more left. Attacking Mightyena isn't worth it, hence the no need for lone dark.
3) You play 5 lightning... But play only 2 cards that should ever see Lightning energy. And those are both Rayquaza deltas.
Since your only energy acceleration is Rotom, you should be spending more time attaching energies with it then dealing damage with its... frankly weak attack.
Jolteon* deals only 40 damage for three energy, when cards like Gardevoir easily do 60 damage AND Power lock at the same time, Gallade has a piece of cake KOing Jolteon, Blaziken can do 80 damage anywhere even with DRE attached... The point is, Jolteon isn't an efficient enough attacker to warrant playing energies for it. Jolteon should be played for its power, which doesn't use energy.
Finally, Rayquaza EX requires a maximum of 2 lightning energy for its big attack--Sky High Claws. Special Circuit is where emphasis usually is, especially since 70 damage Sky High Claws won't KO anything except for stage 1 water pokemon, who are far and thin between. Since the attacks that DEVOUR lightning energies are frankly, not that great, you might as well play Multi Energy. ESPECIALLY since you play Holon's Castform, who can cover the 2 energy needed for Sky High Claws.
4) Lucario's useful attack takes 2 fighting energy. Not the one lightning energy that Rayquaza has. Not the one psychic and two colorless energy of Sceptile ex. 2 fighting energy. You only play 2 fighting energy in the whole deck. Riolu's only attack takes ONLY fighting energy. You're telling us that you want to play Lucario, but in a way that makes Riolu unable to attack, in a way that makes Lucario (AND the LV.X) dependant upon Holon's Castform (2 copies), DRE (1 copy), Scramble (1 copy), or Fighting Energy (2 copies)? Lucario's edge comes from being able to spread damage early game, before the opponent can react. Limited energy makes early game attacking problematic, which renders Lucario's biggest advantage useless.

The redeeming features of your energy line almost come from haphazardly used pokemon: Castform (2 copies) and Rotom (1 copy). Rotom sacrifices a turn, and thus you should know better then to rely on using it for anything more then a jump start. Relying on a single card with only 60 HP to power EVERY pokemon in the deck due to conflicting energy costs is problematic. Castform is almost redeeming, but the fact that it does not speed the energy attachments like Double Rainbow, and the fact that it has a good chance of being your starter pokemon, in a deck where Delta Draw gives you 0 cards every time...

A final problem: Your Furret line. You can get set up with Furret, yes. Furret is an amazing card, that can solve a lot of problems not normally solveable (like having too many specific cards needed for a typical draw engine to find). However, a solo copy of the basic means that it can get prized and the whole line is worthless-no searching at all. A solo copy of the basic means that it won't be your starter pokemon a good amount of the time, which slows down Furret. A solo copy of Furret faces much the same problem. There is a reason why people play 4 Sentrets in their decks (I personally play 3, but that's just me), it's to help them get Furret out, which your deck needs more then most. There's a reason most people play 2 or 3 copies of Furret in their decks; they want copies of the card so it won't be locked up in prizes and be reliable to appear early on without clogging up too much space for late game cards. A final problematic feature with the Furret Reliance, is that Furret and Rotom can't be doing their tricks at the same time. So, are we choosing energy set up (which messy decks HAVE to use), or are we going with more robust set up overall? Maybe we should consider using Pokemon Powers as well, or a way to stop their usage so the opponent doesn't have tricks up their sleeve that we don't.

A FIRM understanding of why cards work together when you play 1-1 copies of cards is vital. A FIRM understanding of selecting the perfect cards that can make effective moves (unlike Mightyena) without sacrificing your energy integrity (unlike Lucario) is needed when choosing partner cards. A FIRM understanding of how your cards react to your opponent's cards is also needed, which is not showcased at this point due to having inflexible pokemon (This card goes here and here only. If the one basic is KOed, I lost the use of 3 whole cards right there. Oh, and we can't forget what happens when our only Energy acceleration card is KOed) and energy combinations. The suggestion of compressing your pokemon lines has been made with the intent of helping you towards that understanding.
You've got time until August for Worlds (Probably the Grinder), and it's certainly possible to find your own deck that you like (Honestly, what's the point if you don't like what you're playing?) and can hold your own with. However, you've gotta be willing to consider problems with your decks, and be capable of refining the deck until you hit only the raw core, and polish that gem until it becomes impenatrable. Trust me, I played an Exeggutor d/Sceptile EX d deck for the Grinder last year, and frankly did awful because I did not carefully consider how to provide the energy for the pokemon, did not consider how I would recover from a surprise KO from something like Infernape, and a general lack of preparation caused problems with a deck that I thought worked well merely because it was effective against one deck (in this case, I seem to recall Eevee-lutions being the ideal matchup :/). It could have been a good idea, but not thought out well enough to handle consistent decks.
Hopefully something of this helps...
