yugioh world championship 2011 structure decks Yu-Gi-Oh! Yu-Gi-Oh! 5D's World Championship 2011:

[F] Mountain Crumble: 120 damage

The activated ability doubles the number of goblins under your control, offering you a constantly increasing board presence alongside more ETB triggers than you know what to do with

Or, if you believe in your ability to strike your opponent down quickly despite their hand, you could employ group hug artifact draw such as Howling Mine or Font of Mythos

Upsides: it's very easy to do a bulk-add of cards, like 4x of a set, it's very fast to search for cads (just start typing the name)

I personally think that era will be looked back upon really fondly for some incredible cards, but thats coming from someone that wasnt around during that era so about as non informed as possible

Phenomenal Limited set (just Khans!) Morph was implemented very well, and manifest was a cool tweak
