Altar of Dementia Discussion

Altar of Dementia has done some serious work for me in the past. Great for Consuming Aberration or whatever big creatures you copy from the opponent.

Hi thatrhetoricguy, thank you for the comment. Actually there is no combo with Altar of Dementia, I literally put it in there as an easy and free way to make use of my drake tokens in case a board wipe managed to get through or if I had to use them for blocking. I have been debating taking it out for some time, however I've never fully sold myself on it!

I am glad my deck has inspired you my friend! I wish you luck and a lot of fun with it!

I actually saw someone mill a person with this deck using Altar of Dementia they had like ten 10/10 creatures that they couldn't attack with and they sacked all of their creatures to mill their opponent. A weird way to win but it was fun to watch. Just a suggestion that you might end up winning with

Altar of Dementia and Eldritch Evolution are both great cards, altar serves the dual purpose of milling yourself to fuel your engine, and milling your opponent in a combo, and eldritch is a solid tutor.

Well... That is helpful.

So the total # of same-turn wincons for Bomberman is 6:

Blind Obedience and Crypt Ghast can be used without Daxos, and the other 4 also act as wincons for the Leonin Relic-Warder + Animate Dead combos.

Note, however, that NONE of these wincons also require Flickering Ward, since you can simply extort LED on re-cast. That could be cut if it's not being useful, as accumulating EXP counters isn't really viable or necessary in cEDH.

(Also, here's a neat trick for the Leonin Relic-Warder combo. If you have Necropotence out, and you really need to try to win that turn, you can pay all but 1 of your life and hope to get LRW and Necromancy. If you do, you can move to the cleanup step, discarding LRW, and flashing in Necromancy in response to Necropotence's exile trigger. You need you wincon in play, of course. If you don't get the cards you need you can always commit seppuku by paying the rest of your life.)

  • This deck has very low curve. 35 lands is probably unnecessary. I'd go down to 32.

  • There's no reason not to include Phyrexian Tower, Volrath's Stronghold, Ancient Tomb, and Cavern of Souls in the landbase.

  • Add Skullclamp as a draw engine. There's enough support for it.

  • If you want Bomberman to be your main wincon, there's no reason you have to wait until your next attack to win with your spirits. Altar of Dementia, Altar of the Brood, and Blasting Station will all do the trick with no additional setup. Using Altar of Dementia on yourself also puts combo pieces in your yard and makes Skullclamp and Replenish more effective.

  • Anguished Unmaking is, in fact, better than Vindicate nearly all the time.

  • Swap Oblivion Ring for Leonin Relic-Warder. They're essentially the same effect, and Warder gets you an extra combo with Animate Dead and friends. (Warder can also be sac'ed to permanent exile while Oring can't be.)

  • Cut Doomwake Giant. This is the top of your curve and it just gives things -1/-1 when it lands. If you really want more board control, Hellfire is much cleaner.

  • Cut Agent of Erebos. We have gravehate on an untapped land now. It's unnecessary. (Scavenger Grounds)

  • If you still need room Thalia, Heretic Cathar and Blind Obedience are both ok to cut. They're ok at slowing opponents down, but not the greatest at it.

  • This last suggestion's a little more for casual play, but for Black/White creature based decks I like to include Westvale Abbey  Flip in the landbase in case he game drags on and I need to recoup some life in an emergency.

shuruga thanks for the look! Altar of Dementia is here to reset my creature into the graveyard while also putting cards from my library into my graveyard. It also serves as a win con if I decide to hit my infinite combo. Ankle Shanker is amazing! But it isn't in this build because of its steep mana cost, and because it is so frequently killed that I spend too many turns wanting to reanimate it instead of something else

Aiding on Meren's Infinite Sacrifice

I also used to run a Meren deck and there are some cards you don't use that I personally found to be quite fun. PREPARE FOR WALL OF WORDS!

(I forget its name atm) The 2CMC Meren that prevents infect and -1/1 counters for infinite persist

Altar of Dementia It is a good sac outlet, mills yourself, or mills your opponents to death (my preferred method of winning) with infinite persist.

Greater Good Kinda is the same thing - sac out, lets you draw and discard junk.

Pattern of Rebirth Kinda was amazing with my deck. Its one flaw is it says the creature needs to hit the yard, so Leyline/RIP effects suck. This has an awesome combo with the next card

Birthing Pod - This card probably is somewhere in your deck, but I didn't see it. It is a great card, it makes your creature curve relevant (kinda important if everything good is a 3 mana thing, nothing on 4, good stuff on 5, for example), and with Pattern, I have won maannny games by patterning my Spore Fog (affectionately known as Fog Frog in my group), and pod-ing it away for 2cmc meren + a persist creature and comboing with a sac outlet.

Mind Slash A little mana intensive, but discard + sacrifice + pain-free thoughtseize was decent.

(this one is a gimmick card but I liked it)

Thoughtpicker Witch- Basically made my "favorite" opponent only draw lands for the majority of the game. Pretty effective on 1v1. Also is an exile win-con when you are infinite persisting. Kind of "win-more," but it can sac itself and come back with Meren EOT to do it again if both cards were non-lands.

TL;DR- Meren "Spore Frog Durdle.dec" was my favorite thing I built for a long while. These are cards I thought were awesome. If you ever wanna try some jank, give these cards a try if you haven't already had them in your deck and I cant see them, or if you feel like a card is being weak and you want to try something new!
