Try checking out the card "Elvish Piper"

Check out fyndhorn elves and elvish piper.

One more thing: USE BASIC LANDS. If you need to cast a spell, but the only lands you can play come in tapped, you won't be able to do anything.

Or maybe indirect damage.

I would recommend you have a specific method of winning, like milling, or unblockable, or that each ally powers up the others. All in all a good deck.

Try looking at "Sword of Body and Mind" It might be useful.

You obviously don't get the point of this deck. It isn't to have normally strong creatures, the point is that each sliver helps every other sliver on the field. It keeps layering until it's unstoppable.
P.S. You are narrow-minded
