Karn's Bastion Discussion

I have a thread, Quick, thoughtful deck help, that can be used to get help should you want it. As for my own suggestions, Evolution Sage and Fathom Mage , as well as Growth-Chamber Guardian are good payoffs for counters. Karn's Bastion also helps in that department

Thank you tllegion01 . I really do like those suggestions. I have been wondering if I should get rid of Contagion Engine . It just seamed to taxing on my mana compared to my other cards. Replacing it with Karn's Bastion is a good idea I think. I will make these changes and see how it goes. Tha is again!

I took another look at your deck this morning after a cup of coffee and if you're interested, this is what I think I would do.

Do away with the Contagion Engine . Far as I can see, they're the only reason you're running 25 lands, which isn't ideal when all of the rest of your spells are a cmc 2 and 3 primarily.

Once you've cut those, drop your land base to 20 instead of 25. If you're looking for another way to proliferate Ludevic's Test Subject  Flip go to 16 islands and throw in 4 Karn's Bastion .

Proliferating doesn't help Thing in the Ice  Flip but a great card for it would be Clockspinning it's a 2 for 1 on Thing in the Ice  Flip since it's and instant and it also has the ability that remove an ice counter. Plus it also interacts with Ludevic's Test Subject  Flip and Chasm Skulker .

After that I would bump up to a full playset of Remand and add another Serum Visions .

Don't know if this is good advice or not, but you're getting it anyways. If you decided to make the changes, let me know how play testing goes

The only reason I straight up refuse to run Domri's Ambush over Thrash / Threat is because I've found the added bonus of possibly generating a token when needed VERY useful in testing.

I tried out Rhythm of the Wild and Growth-Chamber Guardian at various stages of the build and they've never really panned out. Rhythm for fairly obvious reasons. Guardian, however, took some thinking. Eventually I figured that it just cut too much of the token plan to be worth the loss in consistency. If it made tokens of itself for all the triggers and synergies, it'd be an auto-include. Unfortunately it just doesn't work. At least for now.

Karn's Bastion does interest me though. I'll definitely be trying that one out in the near future.

Probably Domri's Ambush over Thrash / Threat as your fight effect, since it buffs the guy as well. Maybe Rhythm of the Wild for fighting against Simic Flash style builds, but even then Domri, Anarch of Bolas is strictly better for what you're going for.

Growth-Chamber Guardian has a nice interaction with the counters synergy to thin the deck and add card advantage, plus a 1 of Karn's Bastion can be a good mana sink.

Infect is one of those decks that can really perform even on a budget.

Llanowar Wastes is a solid budget land option. Its also worth seeing if there is space for Karn's Bastion .

Nurturing Peatland is the most important non-budget land option.

Contagion clasp is too slow in this kind of deck, however since you are already leaning to more midragney value, so I'd look at a card advantage engine in those slots- gambit mainboard or something like Yawgmoth, Thran Physician . I'd also look at taking advantage of cheap hand disruption in black- its a lot easier to land Scale Up if you've just cast Duress . Creature protection is less important since you are running a lot more creatures than traditional, which means 'group' pump spells and wrath-protection should be what you are looking for. pump spells to speed up goldfish or Heroic Intervention / Duress to protect against wipes.

Vector Asp is a turn 1 infect creature that is a little weak to see standard play, but might help your curve. Since this is leaning more towards midrange, Whispering Specter is worth noting for the control matchup. Past that its looking at traditional infect or midrange tools, from Become Immense to all the card advantage spells.
