It came out recently, so its potency is balanced out by the inherent delay of Flip monsters
So knowing this and looking at Slaking, if you decide to use this Pokemon family in a deck, I would highly recommend setting up the entire line on the bench and getting at least 4, probably more, energy cards on Slaking before putting it into the active Pokemon spot
Lovely Labrynth of the Silver Castle Lovely Labrynth of the Silver Castle: A level 8 Dark Fiend-type monster with 2900 ATK and 1900 DEF
Nebulus, Dragon Ruler of Mishaps X DARK Level 2 [ DragonEffect ] ATK 1000 DEF 600 You can discard this card and 1 Dragon or DARK monster, then target 2 of your banished "Dragon Ruler" monsters with different Attributes, except "Nebulus, Dragon Ruler of Mishaps"
This effectively equates to being able to Forage twice, and it draws you a card in the process
The cards for the packs you don't choose can still be obtained by opening more card packs after the tutorial
