"Etoile Cyber" + "Blade Skater"
A Fusion Summon of this card can only be conducted with the above Fusion Material Monsters. While your opponent controls only 1 monster, this card cannot be destroyed by battle. While your opponent controls only 2 monsters, double this card's ATK. While your opponent controls only 3 monsters, negate the effects of your opponent's Spell, Trap, and Effect Monsters.
There are plenty of cards can special summon monsters to your opponent's side of the field, which you can search in-game by typing "opponent's side of the field" in the search function. This gives you more control over Cyber Blader's effect, while also giving your opponent some disadvantage. Shallow Grave can bring back your material monster, and if you use it when your opponent already has 2 monsters, you can use Cyber Blader's third effect, allowing you to negate everything your opponent can use.
Since there are only a limited amount of the fusion material monsters, part of the difficulty can be trying to get them to your hand from your deck, so you're going to need some cards that can search from the deck. You can also bring the occasional Crystal Seer, Dekoichi the Battlechanted Locomotive, or Jar of Greed to get some more draws.
You can use the Ojama fusion monsters to control how many monsters your opponent can summon. If your deck mainly focuses on fusion summon into Cyber Blader, then you only need to bring 1 or 2 ojama monster then use fusion substitute cards like King of the Swamp to get Ojama Knight or King.
