Moving on: Impervious Greatwurm

Impervious Greatwurm + Pariah / Pariah's Shield + Arcbond (targeting the Wurm) + any damage dealt to the Wurm.

Arcbond will try to deal damage to you, but the Pariah effect will redirect it to Impervious Greatwurm . This will mean the Wurm has been damaged again, re-triggering Arcbond . This only goes infinite with an indestructible creature since it can stand being damaged any number of times.

How about Kurgadon .

msanchez13 thanks for your suggestions it really helped out! I was thinking about using Impervious Greatwurm but was worried about finding room for it. I didn't know about Selvala's Stampede but it fits perfectly into the deck.

hkhssweiss, frankly, I think thats enough removal. Ill playtest as it is closer to the end of next week, to have more insight on what might go wrong. But at this point it turns into control deck, and I don't like it. And Sunder ... Will be great in Patron of the Moon deck, but I dont see it here. I'd rather get my hands on Expropriate at this point.

Impervious Greatwurm , Hydroid Krasis or Giant Adephage ?

I don't really like stifle-like cards, as they merely delay inevitable. Perhaps I can cut Incubation/Incogruity in favor of Chaos Warp , since pure anti-creature factor is not that important unless it's Avacyn, Angel of Hope I am dealing with.

Yes, those are good options to be removed. Perhaps, even Wayfarer's Bauble could be a better option than Cultivator's Caravan , since lands are harder to remove. However, I am not sure about Wolfir Silverheart - he is practically 8/8, and +4/+4 is a huge buff to anything - like Impervious Greatwurm which I am considering right now. 20/20 idestructible, with Surrak flashing for surprise, can be huge. It was demoralising for my opponents in every game of playtest to lose 15+ life in a single swoop (turning it into archenemy very fast).

You have a good point. I might need to run a counterspell package, after all.

So far I plan following:

To be removed:

To be added:

And Gyre Engineer is questionably to be swapped with Incubation Druid , since latter can be pumped to give 3 mana and become 3/5 to survive small wipes.

What do you think? I definetely need to clear some space, but right now I am not sure what to remove. So this is what I have: Counterspells:

Only 4 counterspells in 100-card deck... I am really not sure. Maybe Mystic Snake or Frilled Mystic would be better? Boardwipes: Other stuff

I don't run tutors not because they are expensive (Though Wordly Tutor, Gamble and Mystic Tutor are fairly affordable as an upgrade), I don't want to make deck too (uhh) strong. I made Lavinia, Azorius Renegade deck which revolves around getting Knowledge Pool out, and if I draw one of the artifact tutors and have anti-counter in hand, I win, it's only a matter of time. Which is nice to spook new players, but not that great when I play N'th game with same people.

Flooremoji Impervious Greatwurm is sweet but it doesn't bring enough value to replace our current big hitters. It does not leave value behind on the battlefield when we sacrifice it like Worldspine Wurm. As for Emrakul, the Aeons Torn, she speaks for herself, flying, pro nearly everything, annihilator etc. Impervious Greatwurm just boils down to a vanilla 16/16 if we can only have it for 1 turn.
