Dis-Enchant Deck (Historic)

This deck is a lot of fun to play. I've been playing in MTG Arena on Historic with it.
Use Lurrus as Companion and summon to your hand once you have 4 mana and a Kaya's Ghostform in your hand. Never summon Lurrus without the Kaya's. With that, whenever he is killed or exiled, he can summon the Kaya's back to himself. Use all your -x/-x enchantments on opponent's creatures and kill everything. With the Hateful Eidolon's in play you draw a bunch of cards for killing your opponent's creatures giving you more to kill with.

The bonus is that all the enchantments are able to be recast by your Lurrus. Pretty soon, the Death's Approach gets big. I threw in some Feed the Swarm's for pesky enchantments, add/remove depending on the deck you're playing against.
Shadowspear was for both the trample on anything with Eternal Thirst on them, and to remove Hexproof from creatures so you can apply the disenchantments.

Blightbeetle seems like an odd choice, but helps a lot with decks that put creatures in place with large amounts of counters such as Hydras, etc. They make it hard to kill with small disenchants, but beetle stops that. I watch people rage quit out of games when they realize their whole deck relies on counters and their Hydras or Stonecoil Serpents come into play as a 0/0 and die.

No huge creatures in this deck, just deny your oppenent having any creatures in play by killing it every turn. Also good against Mill decks as they are actually helping you get access to more cards to summon from the graveyard.

A few return to your hand cards are included for burn decks that manage to kill the Lurrus, just keep a Find/Witch's Cottage in your hand at all times just in case.
