Go second, hope that you can get enough monsters out to OTK, or stall with Dora.
Shaddoll Trains have been outclassed by Infinitrack/Machina combo Trains, but I miss the old straightforward spam-and-beatdown style of rank-10 trains (and rank-10 trains are a lot cheaper to build, too)
This deck is intended to be a casual/budget altertnative to modern Train decks
...
Jizukiru is a level 10 Kaiju with Light typing that opens up playing El Shaddoll Construct.
Exodius the Ultimate Forbidden Lord is a level 10 and can be useful for recovering monsters.
Skill Drain will disrupt your opponent and turn your main deck monster lineup into massive beaters.
Urgent Schedule is at 1 because the card is relatively expensive and doesn't really mesh well with the level-10 spam style of this particular build. It could probably be omitted entirely.
Have fun out there!
