Coinich, just use the original version of that deck. You have too many pillars.
I think he's worried about getting decked out if water does pack purify. If we stereotypically take 32 cards, water is likely to pack 34 it seems.
For timerclock - the normal dev denial deck has 5, legit was looking at 6. Normally the dev denial deck assumes they live, and it's unlikely against some of the decks. The deck has problems if they blast your first 2 or 3 devourers when you play them, which is what happened in testing as some aether decks pack a lot of lightning. He was occasionally losing in testing against some aether decks because he couldn't get them established fast enough due to lightning kills - that was really the only way he lost.
For dema - note that one of the decks we salvage from has an RT in it, which leaves 5 to come up with from the propaganda if we do that. RT are so useful for us - both in this deck, and as part of rainbows - that building another set of them isn't a bad idea at all. They're just really effective against a lot of problems.
I figure the best thing to do is just make our decks as good as we can, fill in gaps with salvage if possible, and then make luxury choices after that.
