Corrosive Mentor Discussion

Daedalus19876 on Toxic Relationship: Hapatra EDH | *PRIMER*

whistle A lot of comments here!

hurricane219: Protean Hulk has been spectacular in this list, especially when I can Defense of the Heart for it and a sac outlet. I'd highly recommend it to any deck relying on creature-based combos ;)

gdm1989 (first comment): I've thought about including Asceticism before. However, I rarely have the 2 mana open to regenerate, and it doesn't protect token swarms very well. I wish I could find a slot, though...

Odysseus_97:

Corrosive Mentor only affects my things in combat, unfortunately. My non-snake creatures are relatively squishy in this deck, so I don't want them dealing damage to creatures if I can help it (because they'll usually die in the exchange). It is disgusting with Nest of Scarabs, though...

Craterhoof Behemoth is a great card, and even neater since all of my combat-relevant creatures have deathtouch :) but it simply comes down too late in many cases. I initially ran it so I could Natural Order in the late game, but I found that I rarely waited that long once I draw Natural Order. I put Triumph of the Hordes in its slot, and I wish I could play both, but slots are tight...

Archfiend of Ifnir is a card I WANT to use here, but I simply do not have enough discard. I'd have to make discard into a strong subtheme in the deck, and I definitely don't have enough slots to do that reliably...I suppose I could use all 7 relevant cycling lands, but that would slow my curve down pretty hard...

Forgotten Ancient is interesting! I'll keep that in mind haha.

Seshiro the Anointed is a dead 6-mana card if I can't make tokens with Hapatra...

Dusk Urchins was in here until the most recent update. I have not had the chance to test it yet, but I think that Ammit Eternal will prove better in the long run...

Seasons Past is an amazing piece of recursion, I'm surprised more people don't run it. I usually get at least 4 cards back for 6 mana. I wish I could run fetches for increased value...

Bhaal666 and gdm1989: You make extremely good points; I'm glad you're here to help me answer questions on my deck haha. And if I could find a slot for Kamahl, Fist of Krosa I'd probably run him...

Odysseus_97 my own hapatra deck is more casual than this one but I've used most the cards you are asking about.

Corrosive Mentor has been generally very nice for me. Either my creatures get through or i get a few extra snakes, been especially nice for forcing hapatra through. A few times he has been the only black creature so he sucks then but most my creatures are black and gives those silly bugs from Nest of Scarabs more bite. Also great for when people want to attack you until they figure out you benefit more from it.

Archfiend of Ifnir would be great in a discard deck or perhaps The Scorpion God has a good use for him. Sadly to force some usefulness from him you need around 10 discard effects or more for consistency, it just ends up being a subtheme that takes a lot of space and doesn't do enough. better off with Black Sun's Zenith , Carnifex Demon, Contagion Engine, Harbinger of Night, and Midnight Banshee. That seems to be plenty of mass negative counters.

Forgotten Ancient I'm not playing anymore but is hilariously overpowered. He can keep your stuff alive or just pump hapatra and kill someone with commander damage. The multiple uses for the positive counters is really worth it. I'm just testing a more reanimate oriented idea right now.

Dusk Urchins is surprising. Since hapatra drops turn 2 you swing turn 3 and you can place a negative counter here because you want the draw in a few more turns and then turn 4 swing with him for another snake. It is hard to explain how nice he has been but just think about how nice it is to draw 2 or 3 for 3 mana then add in that he gets snakes and might do some damage.

Seshiro the Anointed I removed him because when I want my snakes to get pumped up is also when I want to win. He is useful to have out as long as possible so that you can have deadly 3/3s and consistent draw but that stops a combo I use. If you use the Hapatra, Vizier of Poisons + Blowfly Infestation combo then you need to watch how many pumps you include since they turn it off. If you are not using that then include it as long as the mana doesn't slow you down too much.

I am building my own hapatra deck, what are your thoughts on these cards?

Corrosive Mentor: The wither effect of the black creatures seems very nice, but sadly the snakes are green only. Considering it but what are your thoughts on this card?

Craterhoof Behemoth: Seems like a must in every token deck, you will have an army of tokens so dropping this would be really strong. But might not fit the theme of the deck, but feels wrong not running it. I run From Beyond in my deck as well so i have an extra token generator.

Archfiend of Ifnir: A card i am considering cutting. Its effect is amazing but there are not that many cycling cards that are useful in this deck, so its not often its effect will be used. The only cards you could use with cyclingWhat do you think?

Forgotten Ancient: Might be a good way to remove some -1/-1 counters from your creatures as a form of protection.

Seshiro the Anointed: Good snake lord, and will let you draw cards when a snake hits, isnt this really good in this deck?

Dusk Urchins: I'm not sure about this card, what are your thoughts?

Seasons Past How has this card performed?

Hope for some comments on these card. But what an awesome deck +1.

Hello! Recently I drafted at an FNM and based my deck on Hapatra, Vizier of Poisons and Nest of Scarabs. You see the neat mechanic, right? Now I would like to make a real deck out of it. Here's the prototype: amonkhet -1/-1. It's modern because I would like to integrate a little bit of the wither effect with Necroskitter and Corrosive Mentor. Thanks for any suggestions!

Daedalus19876 Hot damn thats a lot of good suggestions.

Chain Reaction and Blasphemous Act were removed for more spot removal. This way I can keep my creatures. I probably will take your advice and switch it out for Chandra's Ignition. I have that in this deck for a creature with wither so its like a -1/-1 wipe. Or maybe for Decree of Pain.

Fists of the Demigod and Festering Mummy/the little -1's were removed due to better options. The fist would be mostly for adding wither to my creatures which isnt that great in comparisons to Corrosive Mentor as I only have 4 red creatures.

Sneak Attack might have a place but Heartless Summoning is going to kill to many of my creatures and lowers my wither -1's. But Heartstone might be fun! ill playtest.

Horobi, Death's Wail will most likely be added due to the spot removal and the wheel affects will be added. But only the draw 7 ones. Same with Spontaneous Combustion. I didnt even know this was a card!

I think im going to steer away from Spitebellows/Ingot Chewer/Shriekmaw. They are fun! But kinda out of the burn idea.

Great suggestions as always Daedalus19876!

I would take out Corrosive Mentor because it will only give a maximum of six creatures wither. I would put in Nest of Scarabs or Crumbling Ashes.

Thanks for your comment GodCyphus!I get what you're saying, but I noticed that having Crumbling Ashes on the board put's a lot of pressure on my opponant. Especcialy in combination with Corrosive Mentor, Necroskitter and Nest of Scarabs. Because I don't have a lot of removal spells, Crumbling Ashes gives me a solid removal base.

Do you think that focussing on more scarabs is worth losing this constant pressure? Second Harvest and Coat of Arms are great cards, but in order for them to work I have to have a decent amount of scarabs allready on the board. Maybe Parallel Lives as an alternative?
