No worries.

We all make mistakes.

I wouldn't have known that English is not your first language, so you are very proficient with it.

I actually already tested your deck, as you seemed to be a nice person, so here are my suggestions.

This crushes other Creature decks but, as you pointed out, it struggles against Control.

Kambal, Consul of Allocation is a bad card to use against Control as it will just be Countered, or won't stick around.

You might do well to replace it with two more Supernatural Stamina. Control HATES that card.

Vraska's Contempt is a superior card to Never / Return.

It has much more versatility, and is a must play in any Black deck, at the moment.

Blood Sun is an atrocious card to use in Standard, right now.

It makes all of your Opponent's lands come in untapped.

I would use two more Vraska's Contempt instead of those, or add some Lost Legacy to the Sideboard.

You'd be far better off including some Field of Ruin in your Mainboard, to deal with problematic Opponent lands. That will let you get rid of Scavenger Grounds handily enough - a big problem for this deck.

You might also add an Arch of Orazca to your lands. The late game draw it provides helps to close out long matches.

Hope those Comments help you.

Draw well.

This is a terrific idea.

The deck is very original, and is as fun as hell to play.

Argy Thanks for your time! it's appreciated!

I followed all of your advices, with the exeption of Arch of Orazca

While I understand the value of drawing cards in the late game, I fear I might draw it instead of a much needed colored land in the early game and that it would hurt more than help. (I added field in mainboard) so that would be alot of colorless lands.

Guess I'll need to order a few cards after I test it out.

Have a great day!
