Sign in Blood Discussion

TurtleLordMTG on Rakdos, Lord of Burn

18 hours ago

Nice deck! +1 If I would suggest something about the playstyle for Rakdos, Lord of Riots it all depends on how you want the deck to work. If you're laying in for a more casual/focused Rakdos-theme deck than this is it, you've got demons, sacrifice, burn etc so nothing to point out there. I would however just generally recommend more card draw since you might quicky run out of your burnspells. Staff of Nin is a good casual draw card but a little bit too slow. You might want to look into cards like Read the Bones , Damnable Pact , Greed , Sign in Blood , Succumb to Temptation , Grim Haruspex , Underworld Connections are just a few cheap (prizewise) draw spells you could use.

And there's also the option for card-selection cards like Faithless Looting which is a really good one, not card draw per-say but it's still card advantage in a way.

The best draw card in black (and maybe in the whole format at least according to me) is Necropotence . Altough a little expensive it does grant some ridiculous card advantage but that's totally up to you if you want to invest in such.

And lastly, if you ever want to take this deck to a more semi-competitive level, the way for this is to just load the deck with some cheap burn and huge creatures with generic mana as the majority of their cmc (like the eldrazi).

Authority of the Consuls is definitely a sideboard card. Try Dusk Legion Zealot for an early blocker and it replaces itself, or Sign in Blood etc for card advantage.

Necropotence is nearly always better than Sign in Blood unless you really need to keep your draw phase for some reason. In which case Greed is still probably better. Both of these have the advantage of staying in play as reusable draw mechanisms meanwhile Sign in Blood is a one-off.

kamarupa hey thanks for the input! I like Ratchet Bomb and Everlasting Torment as options in the side board. Will add. You think Sign in Blood is better than Plunge into Darkness ? I looked at it and I figured plunge was more flexible, but I'm not sure. Bump in the Night is a good card no doubt but I kinda wanted to stay away from more conventional burn spells and rely more on using my creatures as a way to get reach. May be not as competitive but more fun to me. Priest of Forgotten Gods I have considered. I don't know I feel like I want to be on the attack with my creatures and I feel like priest slows the aggression down. You think it would be a decent sideboard fit? Thanks.

Ratchet Bomb in the sideboard. It hoses tokens and can also help you remove Enchantments. Everlasting Torment might be useful, too.

Fate Transfer would be another way to remove counters from Undying creatures.

Sign in Blood and Bump in the Night seem like possible mainboard fits. Priest of Forgotten Gods also seems worth considering.

If you want an alternative way to abuse Undying creatures, Solemnity fits the bill. Geralf's Messenger + Solemnity + Viscera Seer is an infinite combo.

why not +1 Night's Whisper , -1 Sign in Blood ? The first one is easier to cast.

I think Pack Rat is strictly better than Rat Colony ; I would also take out Defiant Strike for something like Sign in Blood or Sheltering Light . You are very susceptible to board wipes so maybe Dash Hopes to keep opponents honest. I would also consider Throat Slitter , Swarmyard , and Ravenous Rats .

+1, keep it up! Let me know if you want any more insight

mal099 on Rat Bastards

You're essentially playing Mono Black Control, so most of what works for that deck should work for you too. Corrupt to finish the game? Some card draw, to gain even more card advantage, like Sign in Blood or Read the Bones ? I was thinking about Rat Colony , but that's possibly too easy to kill. Rancid Rats might be nice instead of Typhoid Rats , it has better synergy with Okiba-Gang Shinobi . Crypt Rats is always nice, it can clear the board when your opponent has better stuff than you, and can potentially kill your opponent.
