Corrosive Mentor Discussion

I agree mostly with illumfolly. I'll expand a little bit.

Citanul Flute is nice, but it's kind of an expensive tutor. I like Jar of Eyeballs more. Corrosive Mentor used to be in here when I tried a -1/-1 counter subtheme with Necroskitter and friends. It just wasn't enough for me. And I never realized that nonbo with Crypt Rats. I'd rather have Swiftfoot Boots over Whispersilk Cloak, but I took it out for Shred Memory so that I could tutor for the type of protection that I need at that moment. Mesmeric Fiend is nice; I have a similar effect in Brain Maggot, and I should probably get one for the 1v1 version of this deck which leans more heavily on discard. Phyrexian Plaguelord is like a more expensive, big-bodied Plagued Rusalka; Yes, the later has a mana cost to activate it, but I find it worth it. And I've thought about Shadows of the Past, but I don't have room for it over my pure card draw options and Viscera Seer.

I like your suggestions. Most of them could totally have a place in a Shirei deck, but my build doesn't have room for those particulars.

Big Game Hunter -- an obvious include, obviously included here

Citanul Flute -- a bad, win more card

Corrosive Mentor -- yeah sure, could find a place in some decks, makes blocking more valuable. Synergy (undesired here) with Crypt Rats.

Demon of Death's Gate -- also nothing to celebrate, and useless without the alternative cost -- and we have Westvale Abbey  Flip now

Whispersilk Cloak -- sure, for a voltron version, this works well

Hex Parasite -- included in my deck, it's a great card, especially when you can find your Glacial Chasm or when you have over-extended with Smokestack

Lightning Coils -- a fun card, that get's blown up

Mesmeric Fiend -- a great card that I run

Spawning Pool -- sucks, run Blinkmoth Nexus and Inkmoth Nexus, but not this

Ob Nixilis, Unshackled -- it's just a big body, and doesn't even prevent opponents from tutoring

Endless Whispers -- doesn't work, hoses Shirei

No Rest for the Wicked -- I guess, but why not run Phyrexian Reclamation instead

Grave Betrayal -- mediocre

Phyrexian Plaguelord -- a fun card for shirei, but there are cheaper and more useful creature killers. Mostly just too expensive to get out. If you have snowballed to the point of recurring 4 - 5 creatures, then you have won.

Shadows of the Past -- sure yeah, but better/more conventional options... Grim Haruspex family of cards, Viscera Seer is downright better most of the time.

Tragic Slip -- mhm, and Malicious Affliction too

Sorceress Queen -- yeah, moderately useful ability, but the moment you dive into "fun shenanigans" is the moment you lose the game

Hello! I just recently started putting together a Shirei deck, and you seem to have the most thought-out version that I've been able to find on tappedout thus far. As such, I'm curious what you think of some of these cards:

Big Game Hunter: Recur to kill big butts/commanders left and right.

Citanul Flute: In such a toolbox deck, this gets you what you want when you need it.

Corrosive Mentor: Makes your chump blockers that much more annoying.

Demon of Death's Gate: You're still paying 6 life, but a 9/9 flying trampler isn't really something to scoff at.

Whispersilk Cloak: Another protection option for Shirei.

Hex Parasite: Good for getting rid of annoying planeswalkers and slowing down everything else that uses counters. Also makes a good emergency chump blocker.

Lightning Coils: With all of your creatures dying, this could maybe turn into an alternate wincon.

Mesmeric Fiend: With stack shenanigans, you could potentially permanently exile a nonland card of your choice from an opponent's hand once per turn.

Spawning Pool: Turns into a Shirei-able creature until end of turn if needed.

Ob Nixilis, Unshackled: Kinda like Scavenger Drake, but with trample and punishes opponents for decksearching.

Endless Whispers: Because you control both Shirei and Whispers' abilities, you get to chose in what order they occur. As such, you can revive your creatures normally while still stealing your opponent's creatures.

No Rest for the Wicked: A safety net in case someone kills Shirei after you've sacrificed a few creatures.

Grave Betrayal: Kinda like the above, but works even without Shirei out.

Phyrexian Plaguelord: Sac outlet that pokes creatures and gets around indestructibility.

Shadows of the Past: Scrying 1 over and over and over and over...

Tragic Slip: Spot removal that gets around indestructibility.

Sorceress Queen: Tap to allow Shirei, Shizo's Caretaker to save almost any other creature.

Sorry that this is such a wall of text, but I'd really appreciate your input. +1ed, would +2 if I could.

Xica - I don't see how Corrosive Mentor would be of any help.

The interaction he's referring to is that it's impossible for his opponent's creatures to harm his. All creatures have Wither from Everlasting Torment but none of his creatures can have -1/-1 counters placed on them due to Melira, Sylvok Outcast. This is what he was referring to.

Whether or not it's good, ehhh...

Well, why not use Corrosive Mentor instead?
(you would need to protect only 1 card in this case)

P.s.:Many people would not call it a combo, jsut an interestin interaction. And while it can make a deck better, alone its not strong enough (and non-creature deck exist).
