Hello! This is my ideal way to run vaalmonica post LEDE.
I found that although this variant doesn't have a huge turn 1, it can quickly, and consistently gain massive advantage on turn 3 and over.
Since the vaalmonica engine doesn't really need its normal summon, the invoked engine feels pretty good and it provides you with an omni negate + a discard for your pendelum monsters to scale themselves.
A typical combo with Magical Meltdown + a Vaalmonica scale and a spell would go: Magical Meltdown -> Normal Summon Alister -> add invocation -> Link into Artemis -> Fusion Summon Mechaba -> Add back the Alister -> Activate one of the vaalmonica pendelums discarding Alister (Ideally you want to discard Selettrice to add itself back or a trap to use the effect from the graveyard via Zebufera later) -> Set scales (At this point in the combo you want a Selettrice in your hand so you can go through your vaalmonica spells, the main ways to do this are the field spell, invitare or drawing it. Note: Invitare locks you into vaalmonica monster effects so if you have it, use it after you link off Alister so that you can still get to Mechaba. You can also link off the Artemis + Selettrice into I:P Maquerena if you've set your scales already) After you set the scales, pend summon selettrice to get the effect and add vaalmonica scelta -> scelta effect using the take damage effect to grab disarmonia -> disarmonia effect adding back scelta (by now you have 3 resonance counters on dimmono so you can make zebufera -> Link off selettrice to summon zebuferra, set any traps and pass. With this you'll end on selettrice + scelta in hand, mechaba with a free monster negate via selettrice, zebufera to protect your cards and use spell effects in grave, and whatever else was in your opening hand. The following turn you should easily be able to get your field spell + 3 resonance counters on angello to make duralume which pops 3 monsters and can attack 3 times. If you get the 3rd counter while the field spell is on the board, you can steal an opponents monster. By this point you can do basically anything.
Non engine can be whatever you want, i went with some standard cards.
The second invocation can be cut.
For budget options, replace some of the sidedeck with alternatives like pankratops and wait for rarity collection 2 to reprint accesscode talker and apollousa.
S:P can obviously replace the knightmares if you're balling like that. This also gives you room to add more invoked fusions, links or rank 4s.
Overall, the deck isn't spectacular and can't accomplish a lot turn 1 but it has a fun gimmick that can work well at against other rogue decks. And if you're lucky, your opponent wont read your cards.
