I have been working on a deck for years called "Stop hitting yourself". It's just a bunch of stuff that steals your creatures either for a turn or permanently.

Agreed, themes of all kinds can be fun! I think most of my decks have a theme, although sometimes I sacrifice the theme for a little performance.

I think maybe my three favorites:

• Unionize : colorless, Assembly Worker tribal (took me a while to get that to work right! In particular Foundry Inspector + Self Assembler is fun)
• Red Wedding : black/red, vampire tribal with Edgar Markov and Olivia Voldaren (with almost all wedding themed cards)
• Ballroom Blitz : black/red, blitz ability aggro with graveyard return (not the most efficient but pretty fun and efficient!)

I've got a goblin and a cat deck that I love. The cats don't use cat people though, all low mana cost real cats and uses beastmaster ascension to scale them up. Nothing as satisfying as pay 1 mana to drop a sacred cat or two that's suddenly a 6/6 lifelink with embalm.

I built an all black cult deck that thematically is tons of fun, but needs some work to be more reliable. It's stacked with some dark rituals, and mostly clerics thar make up the "cultists" then there's some sacrifice to search your library/return from graveyard/play from hand, and fi ally some massive OP demon cards. You sac the cultists to call out your demons, its fun but it's not perfect.

The best combo I've managed with it was a swamp, dark ritual and 2 priest of gix on my draw, with put down 2 2/1 creatures on turn one and left me with 3 black mana left to spend on three cards left in my hand.

I love building tribal most of the time. I’ve built countless Human decks in every combination of colours.

What format do you play? Would help with recommending some themes and cards.

I play an "Astral drift" mono White deck. I should splice It with Green, but since people Always say that W Is weak, I play It just for spite :D

I like cards with animals. Not anthropomorphic but just snakes, horses, fish, birds etc, even bugs.
