This deck is aimed toward getting Psychic Rover on the field as soon as possible and loop his effect.
Emergency Teleport, Dice Dungeon into Dimension Dice can do that. Foolish Burial can send Rover to GY, as can Spright Sprind sending from the deck, or Gigantic Spright can summon him from deck.
Power Well is a Quick Effect Monster Reborn for ALL Rovers on your GY so their effects start popping off.
Spright Elf can revive Rover as Quick Effect once per turn.
If you summon Rover to an arrow that Topologic Bomber Dragon points to, like with Power Well on opponent's turn, he will destroy all monsters in the main monster zone. This is NOT A ONCE PER TURN. Which makes him and Rover a looping monster wipe.
Spright Pixies is here both as an extra special summon for the plays AND as a battle handtrap to make your Rovers able to crash against people.
Shadowpriestess is the FTK tool here, if you get her and Rover on the field she can keep tributing rover for 800 every time. If Rover fails to come to the field you can fish him back with any of the cards mentioned above and keep going again. Selene Link is here to get Shadowpriestess back from GY, be it from destruction or because of Reasoning and others.
Have fun and best of luck on Rover's effect!!
