Yu-Gi-Oh Guides: Engines

You finish your deck and ask someone to give you feedback and they say "Ummm, I recommend you the Knightmare engine" but you have no idea what they are saying. This guide is all you need to know about the different types of 'engines' used in "Yu-Gi-Oh!". This will teach you guys how to effectively use the different engines, when to use them and what deck they mostly fit in.
