Fusion Dance: The original Gate Guardian is this despite not being a Fusion Monster, consisting of Suijin, Kazejin, and Sanga of the Thunder
Then you should look for events with a more skilled player base, like Regional Qualifiers , Official Tournament Store (OTS) Championships , and YuGiOh
It takes some serious finagling to get your hand size low enough to use Instruct, so Oranguru tends to pair best with decks that discard aggressively, like Ho-Oh- GX , Volcanion, and Night March (in Expanded)

Bafflingly, however, the deck didnt contain a copy of Sliver Hive
