Las Feygas

The Las Feygas (ラスフェイガス Rasufeigasu in the OCG) archetype are a group of EARTH Nymph-Type Pendulum Monsters that use a very unique luck-based strategy. All of them are named after features found in the mystical city of dreams, "Las Feygas", a supernatural version of Las Vegas.

Strategy
The "Las Feygas" cards are very luck-based, but they have an interesting technique for bestowing both good and bad luck. Every Pendulum Monster member has at least one effect that grants an effect, mostly temporary, to another monster on the field. These effects, usually the Pendulum effect of the members, allows for a coin flip or a dice roll to happen when a certain action occurs, and if the result is favorable or unfavorable, something occurs. This can range anywhere from allowing extra cards to be drawn to negating effects to destroying cards to discarding cards to losing ATK and DEF. The best way to use this is to give the bad effects to the opponent's monsters and the good effects to your own. All of the other effects usually have to do with reducing the chances of getting certain results or having their own luck-based effects built in.
