The main feature is bouncing and cloning creatures onto the battlefield taking advantage of their "enter the battlefield" abilities, which can also summon massive amounts of tokens. This deck is still in progress so I'm still looking for suggestions. Trying to keep this budget.
Basic overview of mechanics, combos, and techniques
-Start off with a good early game with good card advantage with Coiling Oracle / Augury Owl + Faerie Impostor. An early Nulltread Gargantuan + a Bond Beetle buff is pretty awesome as well, especially with the mana ramp from Coiling Oracle.
-Things start to get insane once Conjurer's Closet in on the board which can really juice up your "enter the battlefield" creatures. Combo with Thragtusk to gain 5 life and a 3/3 token every turn.
-Another way to juice up your "enter the battlefield" creatures is to clone them. It is preferred to clone the more powerful cards for insane combos. Progenitor Mimic + Hornet Queen swarms the board with hoards of dangerous 1/1 flying deathtouch tokens onto the battlefield. You can keep swarming those tokens since Progenitor Mimic clones every turn, or use Conjurer's Closet.
-Control the board with Dissolve and Familiar's Ruse, a cheap 2 mana instant that can also provide a beneficial bounce to reuse "enter the battlefield". Bring those counter spells back from the graveyard with Eternal Witness and reuse them again. Bounce Eternal Witness to rinse and repeat.
-If your opponent is dragging out the game, populate your clone tokens with Growing Ranks to overwhelm the board trigger more abilities.
Remember, this deck is still a work in progress so I'm still looking for your feedback and suggestions, thanks!
