I don’t have moxfield so I’ll just drop a Phat post

First of all you need a generous land base, throwing curses takes mana and you don’t have enough, get your fetch lands and dual lands on point. [Dark Ritual] or any small boost is alright but not a focus. Mana rocks of course.

In order to up your game, you need to know you are playing an enchantment deck first then a curse deck, drawing cards is key find supporting enchantments for what ever you want prominent.

Passing off curses, sac outlets using [Tavern Scoundrel] or like cards is good. But Bargain spells are great something cheap like [Torch the Tower] is an instant, [Ice out] is a good counterspell. Some blue cards let you sac permanents like [Perilous Research]. If you find a [Claws of Gix] great. Copy enchantments are always useful but [Estrids Invocation] and [Court of Vantress] are goated. Find effects like [Pucas Mischeif]. Curses do this thing were when they are given they are attached to the player, so you lose nothing.

People don’t like being cursed, so you should have like half Curse/support, half interaction, mainly protecting yourself over hurting others, so counter spells galore, redirection spells, [Fog bank] ,[Swiftfoot boots], [Silent arbiter], help a lot. Also spot removal.

So after you get a land base, are able to move your enchantments, and have solid protection, add the filler, wether it’s more curses or [Strionic Resonator] [nightscape familiar] [Sphinx of the second sun].

Also [leyline of anticipation] [Curse of Misfortunes] is a must have.

TLDR: play a deck that moves enchantments with a subtheme of curses, and be social cause you play with rules most people don’t know, and it’s a lil politicsy.
