I made an entire archetype based on the amazing RPG known as Undertale, and I tried to make the effects practical while also representing the lore of the game.

First of all, I'll talk about the basic strategy of the Deck. It's exactly like Undertale, you'll have to choose your path, will you kill everyone or will you spare everyone. And how do I do that? I give the deck a special mechanic, which are Pacifist Counters and Genocide Counters. These counters are generated by the two Pendulum Scales of the deck, Frisk and Chara. And obviously, they are what the deck heavily relies on.

So! Let's look at the cards.

Mt. Ebott - The Field Spell of the Deck.

Frisk and Chara, the two most important cards in the Deck.

Next up we have the Level 4 Squad, Papyrus, Undyne and Mettaton. Each of them has a disruption effect. Besides that effect, Papyrus is also a searcher, while Mettaton and Undyne has lore-related effects.

Then we have Flowey, he's the "Balelynx" of the Deck.

The two Main Deck bosses are Toriel and Asgore. Toriel is for going first, Asgore is the for for going second.

The fun just begins here. We have Alphys who has a recycle effect, which is also a reference to how she turned Mettaton from a ghost into a robot (and she did some "recycling" stuff alright). Not only so, you may have noticed, she's a Tuner! So here's Mettaton EX, the fan favorite. His first effect is an upgrade from the original Mettaton, and the rest are references that he's stronger with a bigger audience.

Then, we get closer to the end of the game! The Final Boss of the Neutral Path, Omega Flowey is here. His effect wipes everything in his path while also completely resetting the game.

Then, we head to the Pacifist path, here's Asriel, which effect will be connected to the next monster.

...that is Asriel God of Hyperdeath! After Asriel awakened, he absorbed everyone's souls (except Frisk) so that is why he's a Fusion Monster. I made him a Contact Fusion so you can bring him out easier without relying on a Spell.

Then, finally, we reach the end of the Pacifist Path, with Asriel's final form. His effects are based on the first and second sequence of his fight.

Now, we head to the Genocide Path! Remember Undyne's effect? Well, if you use her, the Token, and Alphys, you can make Undyne the Undying! The only reference here is that she's a freaking beast.

Next up, Mettaton's final form, Mettaton NEO! This was a disappointment in the game so I decided to make him that too here. BUT! He has potential.

And finally, everyone's favorite, our good buddy Sans. His effect is based on his Judgment, and obviously the final effect is Genocide-exclusive.

Note: I didn't draw these arts, so I will absolutely take no credits for them, all credits go to the original artists for drawing these beautiful arts, also credits to Toby Fox for being an amazing person and making this beautiful game. Finally, thanks everyone for take the time to read this. I really appreciate it.
