Desk is pretty simple to use.
Main objective is to get 2 monsters on the field (such as Rod and Souls) or the sky striker 1 card combo to make Predaplant Verte Anaconda then pay 2000 LP summon Dragoon, win the game. *Eagle Booster is to make them unable to negate Verte.*
The True Name is easy to use if you combo it with Circle or Servant then free Obelisk for a turn. Link him off after battle phase.
If you have Illusion of Chaos and rites in your hand then search Sauravis for a hand negate.
If all else fails just Skill Drain Torrential and recurring beat with DM. EZ.
Game 2: Side in whatever you need to to hard counter them
