Notes & Combos
Definitely a table 500 deck, but I got very, very lucky at the beginning of the event.
The idea is to set Toy Soldier with Toy Box and then send it to the GY with Magicians' Souls, Forbidden Droplet, or another Toy Box. Soldier returns to the field and searches a Watt monster, and then Soldier and Tank become material for Hip Hoshiningen — whose effect adds an extra 2000 damage over the course of all the Watts' attacks.
Alternatively, Tank can tribute itself to summon a Watt from your hand if you already used your Normal Summon.
The only change I've considered is to replace Ultimate Slayer with Photon Sanctuary since the tokens are Thunder and allow Wattrain to search a Watt. Beyond that, Sanctuary is basically just a free Hip Hoshiningen.
