Best. Name. Ever.GG infect

Infect is usually a deck with VERY fast kills. For me I think it is a little too slow. In Modern, by the time you have the chance to get the value out of Rancor or Opt your opponent has multiple blockers and/or is killing you.

You could cut out those cards mentioned above and use things like Berserk which just can crush your opponent out of nowhere.

Berserk is not modern legal.

It amazes me how many non-Modern legal cards get suggested for Modern Infect.

Sorry must have misread something. Thought it said casual or something idk

Sorry if I came off... aggressive. I've just seen Berserk suggested for this deck at least twice, and all over other Modern Infect builds as well. Invigorate is another common suggestion that isn't Modern Legal. Vintage/Legacy and Casual are very different where Infect is concerned. Most other Modern builds don't encounter this because they're not generally viable in Vintage/Legacy, but Infect is at least semi-viable in both Modern and Legacy.

I think you would be better of if you swapped windswept heath for yavima's coast

On the contrary, the more fetches you have the better, because it fuels delve, and clears lands out of your deck for the later game. Also Cathedral of War, Spider Umbra, and Ichorclaw Myr are questionable choices. I think you really need the full playset of Blossoming Defense and Inkmoth Nexus, Vines of Vastwood is also really good. With stuff Push lurking around infect has evolved from being a blitzy type deck to a slower, reactive deck. We need numerous protection spells to keep our low creature count alive.

True but evolving wilds dies the same thing but cheaper and with more targets, the drawback is that it comes in tapped though.

Lands coming into play tapped is a enormous downside, especially in a deck like this where we need the mana available as soon as possible. Another upside of fetches is they can get Breeding Pool for only three life and you have access to both blue and green mana
