Hey everyone, here is my Regigigas/Alolan Muk list (with suggestions from
@HouchinsDJ ). If you don't know already, Regigigas is a basic with 180 HP (new record!) that can deal 160 damage for five [C] energy (a hefty cost, but there is a solution). One draw back is Regigigas's ability, which says it can't attack if Regirock, Registeel, and Regice aren't on your bench. Alolan Muk solves this problem with an ability which says each basic Pokémon in play (including your opponent's) has no abilities. Combined with Kiawe (which allows you to search your deck for four [F] energy and attach them to one of your Pokémon) and Turtonator GX (to help with attaching energy with the GX attack or attacking with Bright Flame/Shell Trap), Regigigas can take out GX and EXs easily.

Some of my personal cards would be Nest Ball (most Pokémon in this deck are basic anyways), Po Town (helps hit the high numbers on evolutions), Random Receiver (gives more chance of finding Kiawe or any other supporter), and Scorched Earth (to help with draw support without abilities).
Hope this helps! Let me know what you think, thanks!
