I think I'm seeing your strategy this looks like a swarm deck, and you have cards to destroy your opponents monsters and stall, I'm guessing to power up for a final attack. I am new to the Synchro style. But I'm not new to swarm decks and field control which you have.

You might add in Heart of Clear Water a common card:

If the equipped monster's ATK is 1300 or higher, this card is destroyed. The monster equipped with this card is not destroyed as a result of battle or by the effect of a card that targets the monster. (Damage calculation is applied normally.)

Might be a good card or try:

Metalsilver Armor a common card:

As long as you control the monster equipped with this card, your opponent cannot use the effect of a Spell, Trap, or Effect Monster that targets 1 monster, except the equipped monster.
