Labrynth Virus Rover

Dynamic focus points.

 - Counter oriented
 - Viruses for turn 2 hand destruction
 - Rover for stall, lucky double destruction, loop discard resource
 - Closer to midrange floodgate than just control floodgate

Key things to remember:
 - Welcome Labrynth locks SP from deck and extra deck to only fiends, until the end of the next turn. Raider's knight, E-Teleport, and Mask Change II cannot be summoned/used afterwards.
 - Vivid tail GY effect locks activation of the card that turn that is returned to hand. You might want to consider the card that you want to return carefully.
 - Rover's extra deck lock does not apply if you use E-Teleport to SP him.
 - Arianna and Arianne's last effect allows a second attacks by resummoning a monster during battle phase.
 - Rover's effect is not once per turn.
