So, spam predaplant spells until you can get a card like predaplant ophrys scorpio, then summon starving venom.
If anything goes wrong then just use the link predaplant or super poly on your opponent.
This whole deck relies on your opponent using a dark type deck. Also super poly bypasses most card negates and predaplants are easily summoned.
Speedroids are there to quick summon Clearwing, Crystalwing or any of the Speedroids as stall cards for your fusion, so your not stuck waiting for super poly.
*Note* Forgot to remove beast king jackal. Its a good card anyways.
