1RR: Put a blaze counter on target land without a blaze counter on it. For as long as that land has a blaze counter on it, it has "At the beginning of your upkeep, this land deals 1 damage to you." (The land continues to burn after Obsidian Fireheart has left the battlefield.)

Makes sense. I feel like harsh mentor only really stops combo with that heavy threat to their life total, forcing miscalculations where they activate an ability then die to direct damage rather than just viewing it as an extra cost. There are a bunch of cards in red that sorta play into the strategy, but they all have problems. Balefire Liege and Stormbreath Dragon is probably too high mana cost , Barbed Shocker does let your opponent refill their hand, but also it forces your opponent to refill their hand, Goblin Razerunners/Obsidian Fireheart or Jaya Ballard, Task Mage are interesting one-ofs to turn late game wasted resources into extra effect, Mindsparker, Zo-Zu the Punisher and Scab-Clan Berserker are of limited use (i'd play them if they cost one less or had 4 toughness), Sin Prodder provides some advantage, but once again, more three drops. Menace is great though. Thats the toolkit that I can remember from my testing, I hope its of some use.

Pretty dark premise you've got here. I'll admit to being the type that wouldn't really have fun against this type of deck, but I can respect the amount of power this would hold over the board.

So saying though, I wonder if you've looked into cards like Traitorous Blood, or similar cards, that would let you take your opponent's stuff before you swing with Rakdos, thus letting you sacrifice their cards in response to his attack trigger, and making them have less options when sacrificing to the commander's damage trigger. Something I've realized that is a really dirty combo within red is Radiate + Word of Seizing to take literally everything from everyone. Doing so might render the damage trigger unnecessary, but I doubt that would be what everyone else cares about at that time eh? Bonus points if you did this in response to what would have been a one sided board wipe.

Also, last idea suggestion; Obsidian Fireheart for a mana sink?

TheRedGoat on Centurion EDH - Variant Commander

I would first ask how well this variant has worked out in your local meta, but I'd also wonder why you have the lists so uneven. I get that you can't list every single one possible for the mono colored ones, but knowing that why not just show some key example commanders to build around for Centurion EDH?

Like you could list just 6 or 7 for color basis, but then add tags for stuff like "mill commanders" or "control/voltron" or whatever seems most fitting. I know a really good one for that burn tag should be Obsidian Fireheart.

Not my Obsidian Fireheart!! Thanks for the help, I might not cut all but it is a start. I wanted to take infinite turns with the combo but you are right, not this deck.

Honestly, you probably need some kind of power booster for the phoenixes. A lot of them are weak and somewhat mana heavy to bring back. Flamewake Phoenix I would try to put to four because that is the easiest one to continuously recur. I like Chandra's Phoenix because she is also somewhat easy to bring back, especially if you replace Pyroclasm with Earthquake. I'm not so sure I like Skred in here since it can only damage creatures. Maybe just a whole bunch of burn spells in its place? Also, while I have a deep love for Obsidian Fireheart (he is one of my favorite all time arts), he seems pretty out of place here. For that mana, maybe consider Flame-Wreathed Phoenix since you'll either get the return ability or a 5/5 beater.

Adamaro on Zo-Zu Hates Your Lands

Thanks for the compliment Suaz14! Here are some more. Please excuse my need to recommend creature spells... It's my favorite card type. I'll be sure to include some non-creatures as well!

You'll probably want to be drawing cards while your opponents are forced to discard cards because they're missing land drops or just barely making the cut at 7 cards in hand. In any case Sandstone Oracle is a budget friendly draw spell. There are plenty of other better options too, but it was just a thought.

I'm not going to be cruel and "suggest" the cards above, that's a lot of clicking around for you to do. So I'll just leave the list here. Hopefully you see something that sparks some interest!
