Is the concept of this archtype inherently flawed or is it the support that is lacking?

[I Hate Snatch Steal]

The whole point of this archtype is to support this card:

 

Here is the support (note that "Level-Up-Magic Fusion Force" also exists, but its not relevant here):

 

 

If this card is normal summoned: you can add 1 "Level-Up-Magic"  card from your deck or graveyard to your hand. You can substitute this card for any 1 Fusion Material Monster. When you do this, the other Fusion Material Monster(s) must be the correct one(s). When using this card as Synchro Material for a Synchro Summon, reduce this card's Level by 2.

 

 

If this card is Normal Summoned: You can target 1 Fusion or Synchro monster in your Graveyard; Special Summon that target, but its effects are negated. If this face-up Attack Position card is targeted for an attack: Change this card to Defense Position.

 

 

When an opponent's monster declares a direct attack: You can Special Summon this card from your hand. During either player's turn, when a card or effect is activated that targets a Fusion, Synchro, or "Level-Up" monster you control (except during the Damage Step) while there is another "Level-Up" card in your graveyard with a different name: You can banish this card from your Graveyard; negate that effect. You can only use this effect of "Level-Up-Knight" once per turn.

 

 

If your opponent controls a monster and you control no monsters, you can Special Summon this card (from your hand). If this card attacks a Defense Position monster, inflict piercing battle damage to your opponent. When this card inflicts battle damage to your opponent: You can add 1 "Level-Up" card from your Deck to your hand except "Level-Up-Assailant".

 

So far my deck based on these cards has done very badly. I want to know if you think its my build or the lack of good support or something else?

I'm thinking that rather than the spell card being able to be returned by it's own effect, you should make your support cards able to add it to your hand instead. I would also recommend having multiple copies with tweaked effects. One that springs to mind, "banish 1 level 4 or lower monster from your graveyard, return one synchro you control to summon one with an increased level equal to the banished monster."

 

Another way you could make adding the spell cards to your hand easier is to make specific "Level-up" synchro monsters, with some effects returning "level up magic" cards to your hand from banish zone or graveyard etc.

 

Another card I would recommend adding is a field spell allowing you to normal summon twice, since majority or your low powered monsters activate when normal summoned.

 

That all being said, I suppose I would have to see the rest of the deck for any more depth. Hope all I've said helps. Good luck finishing the deck. I'm curious to see how it turns out.
